It is Florida Arbor Day and all across the state people will be picking up trees and planting them for the future. It is also the time of year where large reforestation efforts are underway to get the next generation established. Planting trees is one of the most hopeful activities you can do. It takes a long time for a tiny forest seedling to become a titan of the forest. Similarly, a larger nursery grown tree planted in an urban setting takes a long time to get to the large shade tree that is envisioned. Whether in an urban or forest setting getting tree planting right is the difference between success and failure. Today we celebrate Florida Arbor Day, in large part because this is the best time of year to plant trees in our climate. Planting trees in the cold of winter means they can focus on growing and establishing a root system before the leaf and shoot growth they put on in spring. This is why states move their Arbor Day observance and the most southern and warm states like Florida, Louisiana, and Texas have the earliest celebrations.
So, what goes into planting a tree properly? Well, it is a lot more than green side up that is for sure. It takes lots of planning, care, and attention to detail. The specifics are very different when planting thousands of forest seedlings across a tract vs just a few large trees in a park. The basic principles are the same though and we will start with forest trees. For reforestation in forests the journey starts in specialized forest nurseries that produce the millions of trees needed to serve the forest industry of the area. Let’s take a deeper dive into getting tree planting right in this important time of year.
Tree Planting Tips in Forested Settings
Getting tree planting right in forest settings really starts with the tree species and seedlings used. If this is selected wrong, the seedling quality is low, and the seedlings are not handled correctly in shipment and the field; complete planting failures can occur. A failure is very costly as you not only have the cost for this year but the replanting cost the next, plus you lost a year of forest growth. Thankfully, it is very rare now since we know good planting protocols and follow them regularly. Forest seedling nurseries are extremely high tech operations and now provide the best seedlings in the world here in the U.S. The U.S. reforestation system is the envy of the world and the Southeast is the jewel in that crown routinely planting the highest amount of trees of any timber region globally. Entire research divisions at major universities plus state forest agency reforestation sections and the U.S. Forest Service Reforestation Division all work in concert to ensure our forests’ future. That is not to mention the massive private nurseries run by top flight companies that are experts in reforestation and forest management. Landowners and others planting trees now have the best access and reforestation material ever available in private hands, and companies provide the highest quality seedlings available in terms of seedling quality and improved tree genetics. By spending a bit more in reforestation a huge return can be generated when a stand is mature. Landowners can take advantage of this outstanding leap in reforestation technology, but old-fashioned due diligence and good planting technique is key to realize the outcome. First and foremost, the right tree species has to be matched with the right site and range of conditions where it will thrive. Off-site plantings that are not compatible with that species (such as loblolly pine on sandhills) may succeed from a survival standpoint only to fail long term (i.e. stunting and lack of volume development). Care of the seedlings during the planting operation is key to success and establishment though. Seedlings must be stored and cared for properly until planting is completed. Poor techniques will cause issues with root structure and growth and poor care and excessive storage times before planting will cause stress that can result in seedling death or loss of vigor that leads to loss of growth. Plant seedlings right though and you will have an excellent stand. Here are some tips to get tree planting right:
Work closely with a good consulting forester, forest nursery, and or reforestation service provider. Coordinate seedling delivery, storage, and planting well in advance of the operation.
Assess the weather conditions leading up to planting and do not be afraid to cancel if conditions are questionable.
Store seedlings in refrigerated trucks or a refrigerated storage facility (optimal) or tarped in an area that is out of the wind and elements.
Bareroot seedlings are the most sensitive and need to be planted as soon as possible and by skilled crews. Bareroot are prone to J-rooting and other issues if not planted with the correct equipment for the soil conditions and by highly trained and skilled crews. If machine planting ensure test runs are done to make sure the planting trench and packing system are working well and planting seedlings correctly.
Ensure the seedling type and planting conditions are communicated to the crew well ahead of arrival for logistical purposes. A Consulting Forester is invaluable here and results are usually better when a landowner uses a consultant that can coordinate. Issues like planting crews showing up with 4 inch container dibbles (the industry standard) when the landowner has ordered 6 inch containerized seedlings can be a disaster.
Conduct quality control and spacing checks throughout the planting operation to make sure seedlings are in good condition and being planted according to best practices and the planned reforestation operation. Communicate with the crew on changes needed. Crews want to do a good job and usually enjoy working together with the forester or landowner to get the best job done.
Urban Forests

We have passed the forest tree category and we move to the urban forest and what is really the art of individual tree management. Urban forests are very different from natural forests, but they are still forests and the management principles of forestry still apply. The primary difference is planting operations in natural settings involve thousands of trees and usually count on a certain amount of loss. Urban reforestation and tree planting can rely on just a few to several hundred trees depending on the scope. The main difference is urban operations use single large container trees that have been grown for several years in the nursery and will be planted in very specific locations. There is a significant focus on each tree and the investment per tree is huge by comparison. Given this it is highly desirable that each tree live and the expense and investment in each individual tree necessitates this. Urban forests also have ready access to things like irrigation, tailored fertilizer, and many other tree care options to improve establishment. Most Arbor Day activities focus on these urban planting operations and things like tree dedications. To get it right let’s look at what we need to do to get urban trees planted right in our urban forests.
Tree Planting Tips for Urban Areas
Urban trees have a rough life compared to their relatives in the natural forest. Natural forests do not have the myriad of issues that the urban forest does, but that does not mean trees can’t thrive in our urban ecosystem. Here in the Florida Panhandle, we have some of the largest and most densely covered urban forests in our city centers and metropolitan areas. In fact, our urban forest tree cover is some of the highest in the country. This is likely due in large part to our lush semi-tropical forest ecosystem that naturally thrive here. With good management our Urban Forest just sort of forms and towers over our urban landscape. Another factor supporting this is the local community commitment to tree planting and tree care. The vast majority of our incorporated communities are Tree City USA certified and many private HOA communities have HOA rules that require tree cover maintenance. These are good things for our tree cover and our communities are much more livable, enjoyable, and healthy due to our amazing urban forest. To maintain our urban forest though we need to plan tree planting and management, if for now other reason than to replace trees that die or are lost over time. As our area grows and develops new trees need to be planted in urban areas to replace ones lost as the natural forest was converted. Doing this right means more success, healthier trees, and better use of public funds through better survival. Here is what you need to know to plant a tree right in your urban setting.
Right Tree Right Place! Planning is key and far too many times it is overlooked. Urban forests have limited root and crown growing room. Planting a towering Southern Red Oak in an area with only space for 40% of this tree at maturity will not be a success. Yes, that tree is small and dainty now, but in our climate it will grow into a towering tree in no time. Similarly, trees that drop fruit (like Sweetgum) or create a bit of a mess (like Sycamore) may not fit well in an area. Perform a through assessment of the planting spot and determine what size and characteristics are needed. Then compare it with our outstanding variety of native trees and select the right one.
Thoroughly assess the planting site and determine any mitigations that are needed. Locate and determine all utilities, rights of way, and other issues. Remember that utilities have the right to trim any tree that comes into their right of way and that includes roots and branches. If the tree will interfere consider relocation or selecting a smaller tree. Sometimes a tree will tolerate the maintenance activities associated with a utility or right of way but sometimes it will not.
Determine the soil characteristics on site and perform a soil test. This is probably the most overlooked issue, and many people plant trees without any thought to the soil. Since trees are big and tough their site needs often get ignored. It is easy to forget trees have preferences in water depth, PH, density, and nutrient needs. Compaction is particularly a problem in urban settings and a soil test can detect it. If compaction is a problem, develop a plan to mitigate it prior to planting.
Determine if amendments are needed and/or beneficial and apply accordingly. For urban trees preparing a planting hole and root establishment zone is critical to success. Fortunately we have some of the best options and methods of doing this now that we ever have before. Biochar, soil mycorrhizae (beneficial fungi) inoculants, long term release tailored fertilizers, and multiple other options mean a planting hole can be so much more than a hole. Explore the options and select what time and budgets allow, the tree will certainly do much better with good amendments to establish a strong root system early.
Plant the tree properly and using good techniques. You can take a whole class on this and still have some more to gain on technique. It is a much more complex operation than it initially appears. It is more than just getting the tree in the ground straight and level. It starts from the minute the tree arrives from the grower to the maintenance over the establishment years. Common mistakes are too small/too large a hole, incorrect depth, improper backfill and setting, failure to mulch or improper mulching technique.
Arbor Day is a good reminder that trees are a valuable and important part of the world we inhabit. That is true in a pristine forest or under the favorite shade tree at your local golf course. Except for some of the shortest-lived trees most will certainly outlive us. The longest will outlive tens of generations of we humans. Let’s hope that the trees we plant this Arbor Day are successful in establishment and benefit many generations to come.
For many of us in the Florida Panhandle, managing land for and hunting deer are two of the pastimes that we’ll spend the most time and money on each year. I greatly enjoy spending time in the woods and value the opportunity to fill the freezer with high-quality protein and occasionally hang a trophy rack on the wall. Managing a deer herd isn’t without its annoyances though. One of the main complaints I hear each winter from hunters is regarding their food plots not performing as well as they’d like. While all manner of things could be at fault, there are three common reasons for poor food plot performance and a few possible solutions to each – let’s take a look.
Not doing your soil homework. Crops of all kinds, winter food plot forages like small grains, clovers, and ryegrass included, perform best when their pH and nutrition needs are met. The only way to ensure that your food plot plants’ needs are being met is to perform a soil test well before planting. Soil tests show the actual levels of various nutrients (N, P, K, and other essential elements) and pH in your food plots. It is important to remember that even if your soil fertility is adequate or you plan to get it there through fertilizer applications, those nutrients are only available for plants to uptake if your pH is correct (a pH of around 6.5 is ideal for winter grasses and legumes). If your pH is low and needs adjusting, make sure to apply lime several months in advance as it takes time to change your soil’s chemistry.
Too small food plot size. Just like with grazing a cattle pasture, there is a finite amount of grazing pressure that food plots can support and many that I see are overgrazed. So, what can hunters do? If possible, the best solution is to enlarge small food plots to a minimum of ½ acre, preferably larger (1-5 acres). It’s not complicated – the plants we grow in winter wildlife food plots (small grains, ryegrass, clovers, etc.) are extremely palatable to deer and very nutritious. Combine that with greatly reduced native forage options in Panhandle winters, and a quality food plot will often draw large numbers of deer, in excess of what small food plots can bear. To be certain deer pressure is the issue and not poor growing practices, construct exclusionary cages for your food plots; these will allow you to see how your forages grow in the absence of grazing pressure. You might be surprised how good your grass looks with no deer on it and be motivated to increase food plot size accordingly.
Not harvesting enough deer. Even when hunters do all the above correctly, forage performance sometimes lags. This can be a strong indication that too many deer are using the food plot. Stocking rates for deer are difficult to determine because there are many variables involved (native vegetation in your area, hunting pressure around you, etc.). However, if exclusionary cages show quality forage growth, food plots are adequately large, and your forage still struggles, it is likely as simple as too many deer using the forage available. Harvesting only a buck or two a year and no does isn’t going to solve the problem either. In this situation, the solution is often as simple as taking advantage of Florida’s anterless deer harvest periods (doe weekends) to harvest some does, applying for antlerless deer permits if your property meets the qualifications for that program, and filling your freezer with more tasty, nutritious venison.
While there can be many causes for poor winter food plot performance, most hunters can improve their forage situation by simply soil testing and amending accordingly ahead of planting, enlarging food plots where possible, and harvesting a few more deer than they have previously. For more information about winter food plots and any other wildlife management topic, contact your local UF/IFAS Extension office. Happy Hunting!
It’s no secret that fall, October specifically, is the best month for wildflower watching in the Panhandle. From the abundant vibrant yellow-gold display of various Sunflowers, Asters, and Goldenrods to the cosmopolitan bright pinks and purples of Mistflower, Blazing Star, and False Foxglove, local native landscapes light up each year around this time. However, if you’re lucky and know where to look, you can also spot two species, Azure Blue Sage (Salvia azurea) and Forked Bluecurls (Trichostema dichotomum) that sport that rarest of wildflower hues – vivid blue.
Forked Bluecurls begins its flower show in late summer, picking up steam in fall, and reaching its peak now as nights get cool and the days grow short. The species’ flowers are easily among the most unique around. Each flower has two distinct “lips” – the lower lip is white and dotted with blue specks, while the top is distinctly pure blue – with characteristically curled blue stamens rising to preside over the rest of the flower below. Though individual flowers are very small and only bloom in the morning, disappearing by afternoon, they appear by the hundreds and are very striking taken together. Various pollinators, especially bees, also find Forked Bluecurls flowers very attractive and frequent them on cool fall mornings. Though the flowers are obviously the highlight, the rest of the plant is attractive as well, growing to 3’ in height and possessing small, light-green fuzzy leaves. Forked Bluecurls, while not exceedingly common, can be found in sunny, sandy natural areas throughout the Panhandle, including well-drained flatwoods, sandhills, and open, disturbed areas.

The second blue bloomer, Azure Blue Sage, is possibly even more striking in flower than Forked Bluecurls. Aptly named and blooming around the same time as Forked Blue Curls, Azure Blue Sage is a much larger plant (often 4-6’ in height) and holds its abundant sky-blue flowers high above the surrounding landscape. Because of their height and their propensity to occur in bunches, Azure Blue Sage’s brilliant tubular flowers are immediately noticeable to passersby and the myriad bee and butterfly pollinators that visit. Beyond its flowers, Azure Blue Sage is a very unusual looking perennial plant, tall and spindly with dark green, narrow leaves held tightly to square stems, a giveaway of its lineage in the Mint family. The species can be found in similar areas to Forked Bluecurls – natural areas in the Panhandle that possess abundant sunshine and very sandy, well-drained soil.

Both species would make excellent additions to mixed perennial landscapes where the soil and sun conditions were right, as they are exceedingly low-maintenance and have the propensity to reseed themselves from year to year. Unfortunately, they are rarer in the nursery trade than they are in the wild and can only be found occasionally at nurseries specializing in Florida native plants. (Visit PlantRealFlorida.org to find native nurseries in your area!) However, even if you are unable to source a plant for your home, both these somewhat rare, blue-blooming fall beauties, Forked Bluecurls and Azure Blue Sage, are worth searching out in the many State Parks and public natural areas across the Panhandle! For more information about Forked Bluecurls and Azure Blue sage or any other natural resource, horticultural, or agricultural topic, contact your local UF/IFAS County Extension Office. Happy fall wildflower watching!
Bay scallops (Argopecten irradians) have been an important part of the economy of many gulf coast communities within the Florida Big Bend for decades. It was once abundant in all gulf coast counties of the state but beginning in the 1960s populations in many bays began to decline to levels where they are all but nonexistent. The cause of this decline has been associated with many factors including a decline in water quality, a decline in suitable habitat (sea turtle grass beds – Thalassia), and overharvesting. Most likely the cause included all of these. Since the collapse of both the commercial and recreational fishery, Gulf coast communities have been trying to address all three of the stressors above. Multiple monitoring projects are ongoing in the Pensacola Bay area and one of those is the Great Scallop Search.
The Great Scallop Search was developed by Sea Grant Agents in Southwest Florida and expanded, through Florida Sea Grant, to Northwest Florida. In each location volunteers snorkel a 50-meter transect line searching for live bay scallops, as well as monitoring the status of the seagrass habitat. Since 2015 317 volunteers have logged 634 hours surveying 407 50-meter transects in 106 grids in Big Lagoon or Santa Rosa Sound. In that time 4 live scallops have been logged, though we hear anecdotal reports of additional scallops being found in these bodies of water.
Survey Method
Volunteers select and survey one of 11 grids in Big Lagoon, or one of 55 grids in Santa Rosa Sound. Once on site, the volunteers anchor and record preliminary information on the data sheet provided. Two snorkelers enter the water and swim on opposite sides of a 50-meter transect line searching for live scallops. Any live scallop found is measured and returned. The species and density of the seagrass is recorded as well as the presence/absence of macroalgae on that seagrass. Four such transects are surveyed in each grid.

21 surveys were conducted covering 16 grids. 8 grids were surveyed in each body of water.
A total of 77 transects were conducted covering 7,700 m2 and four live scallops were found.
Two of the scallops were found in Big Lagoon and two in Santa Rosa Sound.
All scallops measured between 4-5cm (1.6-2”).
The number of live scallops found this year equaled the total number found over the last eight years.
Most of the transects included a mix of Halodule and Thalassia seagrass ranging from 100% coverage to 5%. The majority of the transects were between 50-100% grass. Four transects had 100% Thalassia. Three of those were in Santa Rosa Sound, one was in Big Lagoon. The diving depth of the volunteers ranged from 0 meters (0 feet) to 2.4 meters (8 feet). Macroalgae was present in 8 of the 21 surveys (38%) but was not abundant in most.

To date we are averaging 35 volunteers each event, surveying 14 of the 55 possible grids (25%). We are averaging 45 transects each year (4500 m2), have logged 407 transects (40,700 m2) and have recorded 8 live scallops (< than one a year).
Discussion
Based on the results since 2016 this year was a record year for live scallops. Whether they are coming back on their own is still to be seen. Being mass spawners, bay scallop need high densities in order to reproduce successfully, and these numbers do not support that. The data, and comments from volunteers, suggest that the grasses look good and dense. Thalassia, a favorite of the bay scallop, appear to be becoming more abundant. This is a good sign.
Though small and few, bay scallops are trying to hold on in Pensacola Bay.

October is Dune Lake Awareness month and as part of the celebration, Walton and Okaloosa County UF/IFAS Extension Agents are joining together to host a Coastal Dune Lake Tour at Western Lake in Grayton Beach State Park. This free event will include a brief lecture and guided tour of the nature trail surrounding the lake. Laura Tiu, Marine Science Agent, will start the tour with a history of the lakes, the unique ecology and some of the local protections. Sheila Dunning, Horticulture Agent, will share information on the unique flora in the dunes including which plants have been used by native Americans and pioneers for food and medicine and the trees we find in the dune landscape surrounding the dune lakes and their adaptations to this sometimes-harsh environment. If you have an interest in our local dune lakes or the tour, you may visit the Walton County Dune Lake website at https://www.co.walton.fl.us/97/Coastal-Dune-Lakes. If you would like to register for this free tour go to https://www.eventbrite.com/e/panhandle-outdoor-live-2023-coastal-dune-lake-lecture-and-trail-tour-tickets-722764316527?aff=oddtdtcreator or use our Facebook event link https://www.facebook.com/events/811943803961304.

A deer darting across a path, a bobwhite calling at sunrise, or the tracks of a coyote in the mud are all fascinating examples of how we enjoy our natural areas. Have you ever wished you could watch wildlife all day to understand the intricate relationships they have with one another? What if you could learn more about their behavior? And their habitat and daily activities?

Dr. Carolina Baruzzi at the UF/IFAS North Florida Research and Education Center and Dr. Corey Callaghan at the UF/IFAS Fort Lauderdale Research and Education Center are launching “ConservationCam”, a new extension program to help you monitor wildlife on your property using camera traps.
Camera traps are a valuable tool for wildlife monitoring. When an animal moves in front of a camera, they trigger a motion sensor to take a picture or video. Camera traps can be set up in multiple ways to target a species or habitat of interest, such as a forest opening or a wildlife burrow. Thanks to their versatility and relative low cost, camera traps are being used in a variety of contexts, for example, understanding the effects of wildlife or habitat management on target species.

The primary goal of ConservationCam is to provide private landowners with access to camera traps, and expert guidance about monitoring wildlife and managing natural resources for biodiversity based on camera trap observations. Armed with this knowledge, landowners can make informed decisions about land management practices that positively impact biodiversity on their property. If you live in the Florida Panhandle, and are interested in using camera traps to monitor wildlife on your property, while learning how to answer different ecological questions, we are gathering expressions of interest through this online form.
