One plant at a time

Our Mission

Our initial work at Durney Key involves mapping both existing mangrove populations and invasive species such as Brazilian pepper, Lead tree, and Australian pine. Recognizing that these invasives currently provide some shoreline stability, we will implement a phased removal process, carefully timed with the planting of native species. 

Cultivation

Mangrove propagules are collected from August-November. Propagules can't be attached they must have fallen off and collected as they wash ashore. Propagules are then sent to several high school where students attend to them until we plant them in the spring. 

Seed Bank Remove

Removing invasive plant species is a slow process and we will start with removing branches with seeds as they form. This will allow the plant to still assist in anchoring the shoreline but remove any new potential growth from seeds. 

Spring Transplanting

Propagules sent to classrooms around Pasco County will make their journey back to our shoreline. Students will plant mangroves and spartina in designated zones along the Durney Key shoreline.

Mangrove Tree Rings

Mangrove planting rings will aid in tracking planted mangrove success, distinguishing them from natural recruitment, deterring foot traffic, and stabilizing seedlings until their roots establish. 

How you can help

Please stay on the trails we are creating. Bring a pale of water and help water our mangroves. We need native upland plants that are salt tolerant, if you are able to donate, please reach out to us.  We welcome your inquiries and feedback at Durney Key. Whether you have questions about our research initiatives, wish to collaborate, or simply want to learn more about our work, please do not hesitate to reach out.  

Anchoring our future

Mangroves

Avicennia germinans

Rhizophora mangle

 Mangroves are unique coastal trees that have several distinctive adaptations

Salt Tolerance: Mangroves can live in salty or brackish water. They have various adaptations to manage high salinity, such as filtering out salt at the root level or excreting it through their leaves

Viviparous Reproduction: Mangroves reproduce through a process called vivipary, where seeds germinate while still attached to the parent tree. These seedlings, or propagules, eventually drop off and float until they find a suitable spot to root

Rhizophora mangle

Avicennia germinans

Rhizophora mangle

 Red mangroves, scientifically known as Rhizophora mangle, are fascinating salt-tolerant evergreen trees that thrive in coastal and estuarine ecosystems. They are easily recognizable by their unique prop roots, which arch above the water level, providing extra support and oxygen intake 

Avicennia germinans

Avicennia germinans

Laguncularia racemosa

Black mangroves, scientifically known as Avicennia germinans, are another fascinating species of mangrove trees. Here are some key points about them. Black mangroves are found in tropical and subtropical regions, including the southern United States, the Caribbean, Central and South America, and parts of West Africa. They typically grow in the intertidal zone, between red and white mangrove

Laguncularia racemosa

Laguncularia racemosa

Laguncularia racemosa

  White mangroves, scientifically known as Laguncularia racemosa, are another important species of mangrove trees Ecological Importance: Like other mangroves, white mangroves play a crucial role in coastal ecosystems by stabilizing shorelines, reducing erosion, and providing habitat for various marine and terrestrial species

. Their root systems also help in filtering pollutants from the water 

Spartina alternaflora

Laguncularia racemosa

Spartina alternaflora

 Spartina alterniflora, also known as smooth cordgrass or saltmarsh cordgrass, is a perennial grass commonly found in intertidal wetlands, particularly estuarine salt marshes

 Spartina alterniflora is native to the Atlantic coast of the US and Gulf of Mexico.

This species plays a crucial role in coastal ecosystems by stabilizing shorelines, accumulating sediment, and providing habitat for various marine organisms. It acts as an environmental engineer, helping to build up the land at the seaward edge.

Mangrove Tree Rings

Laguncularia racemosa

Spartina alternaflora

 Mangrove tree rings will help protect the plants and the shoreline. The surface of the rings will provide great habitat for oyster spat to stick to and create a better shoreline.

 

Brazilian Pepper

Brazilian Pepper

Brazilian Pepper

 

Brazilian pepper (Schinus terebinthifolia) is an invasive plant species native to South America. It was introduced to the United States as an ornamental plant in the 1800s and has since become a major problem in Florida and other warm regions.

Here's a quick summary of why it's a problem:

  • Aggressive growth: It grows rapidly and forms dense thickets, outcompeting native plants.
  • Ecological damage: It displaces native vegetation, reducing biodiversity and harming wildlife.
  • Economic impact: It infests agricultural lands, impacting crop production and requiring costly control measures.
  • Health risks: Its pollen can trigger respiratory allergies, and contact with the sap can cause skin irritation.

Brazilian pepper is a serious threat to Florida's ecosystems and economy. It's important to be aware of this invasive species and take steps to control its spread. .

 

Australian Pine

Brazilian Pepper

Brazilian Pepper

  

It's a real problem in Florida. Here's a quick summary of why Australian Pine is considered invasive:

  • Fast and furious growth: Australian pines grow incredibly quickly, allowing them to outcompete native plants for sunlight, water, and nutrients.
  • Dense shade: They create a thick canopy that blocks sunlight, preventing native plants from growing underneath.
  • Chemical warfare: Their leaves contain chemicals that inhibit the growth of other plants, further reducing biodiversity.
  • Shallow roots: Their root systems are shallow, making them prone to toppling in storms and contributing to beach erosion.
  • Habitat destruction: They displace native plant communities, which disrupts the food and shelter sources that native wildlife rely on.

They're particularly harmful to coastal areas, where they interfere with sea turtle nesting and exacerbate erosion.

 

Lead Tree

Brazilian Pepper

Lead Tree

  

Lead trees ( Leucaena leucocephala) are invasive in Florida primarily because they are aggressive competitors that:

  • Grow rapidly: They establish themselves quickly and reach maturity fast, giving them an edge over native plants.
  • Form dense thickets: Their growth habit creates dense canopies that shade out and outcompete native vegetation for sunlight, water, and nutrients.
  • Prolific seed production: They produce abundant seeds that are easily dispersed by wind, water, and animals, leading to rapid spread and new infestations.
  • Adaptability: They can tolerate a wide range of soil conditions and are drought-resistant, allowing them to thrive in various habitats across Florida.

Essentially, lead trees are ecological bullies that disrupt natural ecosystems by displacing native flora, reducing biodiversity, and altering habitat structure. This can have cascading effects on wildlife that depend on native plants for food and shelter.
