Invasive Species

Invasive Species

Invasive species are plants, animals, or other organisms that are foreign to a particular environment, and whose introduction may be detrimental when invasives compete with or consume native species. Invasive species in Caribbean reefs include lionfish, batfish, and tubastraea coral.

Agriculture, aquaculture and forestry policies regulate and control agriculture, aquaculture and forestry. The Aquaculture sector is involved in the raising and production of aquatic animals and plants in controlled environments. Aquarium and Pet Trade involves the preservation and exhibition of aquatic species for public view or individual hobbies, and the sale of animals. Ballast water discharges by ships can have a negative impact on the marine environment. Biochemical & genetic resources are the naturally available novel biochemicals and genetic information found in coral reef organisms that can be utilized for animal breeding or development of biotechnology. Biological Addition refers to anthropogenic inputs of a biological nature into the reef ecosystem, including artificial habitat, domestic animal waste, supplemental feeding, and escape or release of non-native species. Contact Uses, such as biological additions, physical damage, and biological harvesting, are activities in which humans create pressures through direct contact with the ecosystem. Cultural services are the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, recreational opportunities, aesthetic experiences, sense of place, and educational and research opportunities. Culture sectors contribute to the social, emotional, and intellectual well-being of the community. Discharge limitations are responses to regulate and control the discharge of pollutants and the use of chemicals. Discharges are the intentional or unintentional distribution of chemicals, debris, or other pollution, into the environment as a consequence of human activities. Ecosystem monitoring and restoration refers to responses to directly alter the condition of the reef ecosystem through restoration or remediation activities, setting limits on degradation through biological criteria or water quality criteria, or improving knowledge through monitoring, mapping, and scientific research. Ecosystem services are the benefits people obtain from ecosystems . Environmental education refers to organized efforts to teach about how natural environments function and, particularly, how human beings can manage their behavior and ecosystems in order to live sustainably. The Escape and Release of Non-Natives pertains to the introduction of non-native and potentially invasive species into the coral reef ecosystem. The Food and Raw Materials sector includes groups that harvest natural resources from the earth, including agriculture, aquaculture, fishing, forestry, mining, and the oil and gas industry. Infrastructural sectors provide the physical, organizational, and technical support for the economy to function, including construction, utilities, transportation, finance, manufacturing, wholesale and retail trade, and technical services. Invasive species are plants, animals, or other organisms that are foreign to a particular environment, and whose introduction may be detrimental when invasives compete with or consume native species. Marine products are non-food goods derived from reefs that promote human well-being (e.g, aquarium fish or ornamental resources) and human health (e.g., pharmaceuticals and cosmetics). The Reef Ecosystem includes a suite of abiotic variables that form the physical and chemical environment. Waterborne point source discharges are pollution from a discernible, confined conveyance, such as a pipe, vehicle, ship, or animal feeding operation that directly enter the aquatic environment into streams or direct discharge into coastal waters. Pressures are human activities that create stress on the environment. Provisioning services are the products or ecosystem goods obtained from ecosystems, including seafood, genetic and biochemical resources, pharmaceuticals, ornamental resources, and water resources. Aesthetic & recreational value pertains to the value derived from the visual beauty and recreational opportunities provided by a natural ecosystem, including an assemblage of diverse, healthy, colorful, or unique species. The state of the Reef Ecosystem is the condition, in terms of quantity and quality, of the abiotic and biotic components including physical, chemical, and biological variables. Reef Habitat is the abundance, distribution, and condition of the benthic components of the reef ecosystem. Reef Inhabitants are all of the motile components of the reef ecosystem, including fish, invertebrates, marine reptiles and mammals, and are quantified by their abundance, distribution, and condition. Reef Life is the abundance, distribution, and condition of the biological components of the coral reef ecosystem. Regulating Services are benefits obtained from ecosystem processes that regulate the environment, including erosion regulation, natural hazard regulation, and climate regulation. Resource use management pertains to responses to regulate or limit contact activities that may directly impact coastal species through harvesting or physical damage. Responses are actions taken by groups or individuals in society and government to prevent, compensate, ameliorate or adapt to changes in Ecosystem Services or their perceived value. Socio-Economic Drivers include the sectors that fulfill human needs for Food & Raw Materials, Water, Shelter, Health, Culture, and Security, and the Infrastructure that supports the sectors. Supporting services are ecological processes that indirectly benefit humans by maintaining a functional ecosystem for the production of other ecosystem goods and services. Transportation management includes policies, regulations, and zoning designed to control the distribution and intensity of transportation networks, including roads and shipping channels, and vehicles, including cars, boats, and ships. Water Transportation pertains to all transportation of people and goods via waterways.

CMap Description

Invasive species may contribute to the diversity and aesthetic value of the reef, but often compete with or consume native species, and alter native communities. Collectors of exotic species, such as the aquarium and pet trade, or ballast water discharges from international ships may lead to the introduction of invasive species that compete with native species. Aquaculture facilities also pose a risk of accidentally releasing cultured species into wild populations. Monitoring and scientific research can be used to track invasive species and better understand their impact on native populations. Ballast discharges can be controlled through point-source regulations. Environmental education can be used to educate individuals against accidental or intentional introductions of exotic species. Remediation may be required to directly remove invasive species where they are severely impacting native species.

Fishing & Harvesting Management: Research Low-impact Fishing Gear & Methods Facilitating research to develop gear designs and fishing methods that minimize impacts is multifaceted. Ideal fishing gear is selective for the target species and sizes, with negligible direct or indirect impact on non-target species, sizes and habitats; but also efficient, giving quality, high catches at the lowest possible cost. Newly developed low-impact gear allows fishermen to fulfill their needs, providing food and income, while lessening the unintended environmental impact of those activities, like by-catch. Before an agency should promote new fishing gear or methods research is important to ensure there are no un-intended environmental tradeoffs. Biodegradable fishing line, modified traps, and buoy lines are examples of gear types that could be studied. NOAA Marine Sanctuary Program. 2007.

Marine Zoning: Utilize Marine Protected Areas for Research and Monitoring Research and monitoring of marine protected areas determine the degree to which the zones meet goals and objectives for protecting natural resources, as well as human-use patterns, attitudes and compliance. Once data is gathered from within the protected zone it can than be compared to comprable data from outside the protected zone, as a control. It is necessary to compile and review data on use patterns to determine where additional Special-Use Areas would be appropriate. Research in the protected area should be non-invasive. It is important to make the protected area available for external research as well. NOAA Marine Sanctuary Program. 2007. Florida Keys National Marine Sanctuary revised management plan.

Monitor & Research: Research and Monitor Wetlands This management option involves monitoring and research of mangroves, both for biotic and abiotic factors. Some biotic factors include disease, species, invasive species, abundance, age and leaf litter. Important abiotic factors include sedimentation rates, types and causes of turbidity, and soil chemistry. The activity would document changes to the extent of mangrove vegetation by using historical aerial photography and other records. Wetland nutrient and contaminant processing productivity depends on maintaining a balance and not exceeding thresholds. There remain many unknowns in wetland restoration as to optimal capacity and how to achieve this. NOAA Marine Sanctuary Program. 2007. Florida Keys National Marine Sanctuary revised management plan.

Regulatory Review and Development: Evaluate Exotic Species Regulations The release of exotic species is already prohibited in many areas. Often these regulations do not consider exotic species released in ballast water. Regulations on discharge of ship ballast water containing exotic or non-indigenous species is therefore an area for regulatory improvement. NOAA Marine Sanctuary Program. 2007.

Regulatory Review and Development: Evaluate Aquaculture/Mariculture Regulations This will help determine if there is a need to establish mariculture operations regulations and proceed accordingly. This would help satisfy the commercial demand for fish while taking pressure off of the wild species. Such regulations should consider where, when and what species of mariculture are allowable. The environmental impact mariculture has can vary depending on current, depth and distance to land, making location and even season important. The species being cultured is also an important consideration, especially if they are non-native or different genetically from the local natural population as escapes may occur.

Resource Use Management: Prevent Introduction of Invasive Species Preventing the introduction of invasive species involves public awareness of the invasive species, minimizing modes and prone areas for invasion, and detecting small populations for early eradication. Some common modes of terrestrial transportation include livestock and domestic animals, mowing equipment, and firewood. Clean equipment before transport to a new location. Remove soil from plants, and plant bare-root. Use high grade seed and weed free livestock feeds. Reduce opportunities for invasive plants by keeping native plant populations strong and healthy and seeding in cover crops to reduce barren soil.

Restoration: Removal of Invasive Algae Benthic organisms on reefs maintain a delicate balance competing for space. In many areas, the competition between coral and algae has fallen out of balance due to confounding factors. Factors such as decreased herbivorous fish and invertebrates, and invasive algae species have allowed faster growing algae to take over many reefs, often growing into smothering mats that cover and kill coral. In Hawaii, there has been some success physically removing invasive algae such as Kappaphycus using underwater vacuums extended down from barges or volunteer events in shallower areas.

Restoration: Beach Vegatation Restoration Natural beaches are often host to important costal dune ecosystems. Due to tourism, much of the vegetation that comprises these dune ecosystems may be compromised. The natural vegetation provides an important ecosystem service, with roots providing deep stabilization against physical damage and removal of that sand. Without such vegetation sand and dunes can be completely washed away during hurricanes and other surge events. The dunes themselves offer some protection to nearby inland infrastructure during these same storm events. When the beach past the dunes is for public access it is beneficial to build raised walk-overs over the dune vegetation. This prevents trampling, which leads to dune blowouts.

Water Quality Management: Pet Waste Cleanup Ordinance & Education In residential areas, pet waste can contributes to the large amount of nutrients and pathogens that enter the water through stormwater runoff. This is especially useful in regions such as Gu�nica, Puerto Rico where there are a lot of stray dogs. Education for pet-owners and possible ordinance would help decrease harmful pathogens reaching corals through stormwater runoff and reduce eutrophication. Center for Watershed Protection. 2008.
