Scientists in the Field

Kathleen Smith with Florida Fish & Wildlife Conservation Commission is the lead wildlife biologist for the CREW WEA.

There is a lot of science that happens at CREW. Did you know that the Florida Fish and Wildlife Conservation Commission (FWC) employs two full time wildlife biologists to perform wildlife monitoring throughout the CREW project? Their research combines in-depth field work, data collection and long-term trend analysis to detect changes over time in animal and plant species because of land management activities.

Photo-monitoring, established at CREW in 2005 with additional sites added since then, is just one of many fascinating projects that take place in the interior lands of CREW. Stationary photo points are in three units of CREW where the Majority of the land management activities take place: Corkscrew Marsh, Cypress Dome Trails, and Flint Pen Strand.

FWC wildlife biologists Kathleen Smith and Lauren Plussa navigate the fire-breaker roads developed by the South Florida Water Management District through CREW Flint Pen Strand.

FWC biologists use a standardized data collection method at each photo point throughout the process. Starting with a map of the photo points, they embark early in the morning to beat the heat and the summer storms. On the route through north Flint Pen Strand, a swamp buggy is needed to reach interior photo points and a pole saw is required to clear and navigate the thick midstory of fast growing Florida foliage.

Lauren Plussa clears the overgrown path for our buggy to pass and for hunt permit holders that may use the same trail during the upcoming hunt season.

There is a lot that goes into photo-monitoring. The most important component involves photographing the vegetation in the exact same spot, twice a year (wet season and dry season) over an extended period of time. For each photo, biologists place the camera on a platform at a fixed height, and then using a 16.5-foot rope, biologists walk a field helper to the end of the rope, placing that helper at the same fixed distance away from the camera in each photo. This field helper holds a sign with the number and cardinal direction of each photo, as well as a vegetation measuring stick that measures the height of the surrounding vegetation. These photos serve as representative snapshots of vegetative changes on the CREW lands over time.

Biologists also use a densiometer which looks like a concave-shaped mirror that reflects the canopy cover above them to determine the density of tree canopy and mark changes in canopy density over time.

After collecting the data they return to the comfort of the office field station to compile the results and compare this year with previously collected data. The post-field work analyses is the more complex and time-consuming part of field work, but it provides a complete picture of the vegetative changes over time on the CREW Management Area

Trees – why do we love them?

Volunteer Perspective Series

Written by Nan Mattingly

          In the 60,000-acre Corkscrew Regional Ecosystem Watershed (CREW) Project, you’ll find a wide variety of trees. The stars of the show are bald cypresses that dominate Bird Rookery Swamp and slash pines found throughout the CREW Project, as well as red maples that provide vivid color to the predominantly green and brown landscape. Of course, you’ll also see many sabal (or cabbage) palms, our state tree. All of the trees in CREW help filter and protect the water that soaks into the aquifer that spans Lee and Collier counties. This aquifer stores the water that we need for just about every aspect of life in southwest Florida.

          Aside from their contribution to our vital water supply, trees in the CREW Project also provide a myriad of less visible services that enrich and improve our environment. Some of those services are:

  • Natural air conditioning: when you walk under a canopy of mature trees (which you’ll find in all four CREW trail systems) you immediately notice a drop in temperature, as much as six to eight degrees. That’s a real gift in the summer months. (Trees strategically planted to shade your house can lower your electric bill by as much as 15 %.)
  • Habitat for wildlife: bird watchers can delight in the variety of birds on show among the trees, from colorful songbirds to impressive raptors (hawks, vultures, crested caracaras, etc.) to charming wading birds such as great blue herons, ibises, and egrets. CREW lands also attract fascinating seasonal visitors such as swallow-tailed kites and wood storks. Florida panthers, bears, bobcats and others rely on heavily forested areas for concealment of their dens and for hunting grounds. And if you see a mature tree that is missing a long chunk of its bark, bears may have been using that tree to scratch their backs.        
  • Capture and storage of carbon dioxide emissions: trees are the most efficient carbon capture machines in the world. Through photosynthesis, trees absorb carbon dioxide and store it in their leaves, stems and roots. That carbon provides some of the energy that trees need to grow and leaf out. Carbon dioxide traps heat in the environment, so the trees in CREW can help lower the temperature in surrounding areas. According to the Environmental Protection Agency, all the vegetation in the U.S. (especially trees) absorbed 11 % of carbon emissions in 2017.         
  • Rich, refreshing environment for hikers: CREW offers four trail systems, all of which feature some trails that are lined and shaded by mature trees. When you’ve hiked deep into the woods, the lush, cool and green atmosphere created by trees is more invigorating than a session at the gym and more reassuring than a session with a therapist.

          All of these practical reasons for appreciating trees are sensible and important. But it may be the natural grace and beauty of trees that most attracts us to them.

Photo Scavenger Hunt

The April Edition

During the CREW trails closure we asked CREW Trust Facebook fans to send in their best photos from before the closure. We called it the CREW Trust Photo Scavenger Hunt and the response was impressive.

Brenda Brooks, our Executive Director will be in the Main parking lot (the big lot). You can catch up with Allison Vincent, our Communications Director out on the trails. If you’re into more bird watching and less hiking, be sure to head over to the Lakes Parking lot to say HI to our Education Coordinator, Jayne Johnston. Binoculars and guides will be available for you!

We will practice safe social distancing with face-cover, keeping at least 6 feet of separation at all times, and avoiding the trail “gauntlet” while hiking (see infographic above)

If you haven’t been to the newest CREW trail system here’s the address for CREW Flint Pen Strand – 15970 Bonita Beach Road, Bonita Springs, FL 34135 (left on dirt road)

See you on the CREW trails this Saturday!

All CREW Trails OPEN- April 29, 2020

You’ve all waited patiently for your favorite CREW trails to reopen. Well, the day has arrived!

You can immediately head out to the trails to enjoy the fresh air at all four CREW trail systems: Bird Rookery Swamp Trail, CREW Marsh Trails, Cypress Dome Trails and Flint Pen Strand Trails.

Please remember we all need to practice social distancing, even on the trails.

Consider the “bottleneck” areas, like the parking lot or boardwalks as spaces to be especially considerate of others space.

We will continue to update our media pages as we learn more from the South Florida Water Management District.

Sprucing Up the CREW Trails

Before the trail closure on April 4th, CREW Trust staff, volunteers, and Florida Gulf Coast University (FGCU) students were out in full force finishing up some big projects during the final cool months. 

Several projects include the Wild Coffee Trail/White Trail revitalization at the CREW Cypress Dome Trails, the installation of new green and yellow post trail markers at the CREW Cypress Dome Trails, widening the Popash Trail at the CREW Marsh Trails, and an Adopt-A-Road cleanup along Corkscrew Rd. 

Our CREW trails consistently undergo huge improvements thanks to our dedicated volunteers and students that know how to complete a project from start to finish. 

Currently, trails are closed to the public and CREW Trust volunteers, but this does not mean that the volunteers have lost their enthusiasm. They have found many creative ways to help throughout the Florida #stayathome order!

Partner Spotlight

The South Florida Water Management District (SFWMD)

SFWMD Prescribed Fire at CREW Cypress Dome Trail

You may already know the general story of the CREW Project. In 1989, a conservation minded group of go-getters banded together to protect the land that makes up the CREW Project today. What you may not know is how the land was chosen and how the South Florida Water Management District (SFWMD) emerged as the primary land owner and land manager of the CREW Project’s 60,000 acres.

In the 1980s, after several years of drought caused wells to go dry, the Lee County Board of County Commissioners applied to the state Save Our Rivers Program land acquisition program (later becoming the Conservation and Recreational Lands Program (CARL) and now known as Florida Forever), asking the state to purchase Flint Pen Strand for a water recharge area to ensure a better water supply for southern Lee County. 

At the same time, National Audubon Society’s Corkscrew Swamp Sanctuary and the Conservancy of Southwest Florida also asked the state to purchase Bird Rookery Swamp to protect the southern and western edges of the Corkscrew Swamp Sanctuary. 

The state looked at both applications and noticed that the two parcels of land were near each other. They studied the area further, discovered there was an entire undisturbed watershed system and determined that the whole system needed to be protected.

Parcel by parcel, the National Audubon Society, Lee and Collier counties, and the state began acquiring parcels within the watershed. The state turned over land management duties to the SFWMD after acquisition. The SFWMD manages their lands to support continued or improved water flow for the benefit of Lee and Collier County citizens.

It is truly a cooperative effort and the key to our success has been partners like the SFWMD. The CREW Trust thanks you!
