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.
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.
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.
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 planting rings will aid in tracking planted mangrove success, distinguishing them from natural recruitment, deterring foot traffic, and stabilizing seedlings until their roots establish.
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.
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
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
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
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 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 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 (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:
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. .
It's a real problem in Florida. Here's a quick summary of why Australian Pine is considered invasive:
They're particularly harmful to coastal areas, where they interfere with sea turtle nesting and exacerbate erosion.
Lead trees ( Leucaena leucocephala) are invasive in Florida primarily because they are aggressive competitors that:
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.
