Caribbean Conservation Practice Specification Guide
BACKGROUND All land provides habitat for some wildlife species. Term “wildlife” means non-domesticated birds, fish, reptiles, amphibians, invertebrates, and mammals. The term “wildlife habitat” means the aquatic and terrestrial environments required for fish and wildlife to complete their life cycles, providing air, food, cover, water, and spatial requirements. Not all elements may apply to every habitat type.
Food – Types of food, quantity, quality, distribution, and seasonal availability;
Cover - Types of cover (for nesting, brood rearing, fawning, resting, roosting, escape from predators, summer shade, travel corridors), quantity, quality, and distribution;
Water - Quantity, quality, accessibility, and seasonal availability;
Interspersion and Connectedness – Distance and connections to food, cover, and water.
Cropland, pastureland and woodland all produce and support wildlife to the extent of providing some or all of the basic habitat elements. Landowners can address some habitat shortcomings on their property by providing food plots, nest boxes, brush piles, watering facilities, etc. However, maintaining a sustainable population often requires cooperation of multiple landowners. Simply having considerable amounts of food, cover, or water does not ensure a sustainable wildlife population. Within any area, large quantities of potential food, water, or cover may go unused because they are too far apart in relation to the customary travels of the animals in an area. An animal could travel a long distance to find water if necessary, but it would do little good if the animal was preyed upon along the way. Properly arranging the habitat components across a landscape is important to ensure that each component benefits the species of concern. Accomplishing this goal requires an understanding of the specific habitat needs of the managed species.
Habitat value depends on the quality, quantity, and interspersion of food, water, cover, and living space. To provide complete habitat, all requirements for the target species must be found within its home range.
Upland Wildlife Habitat Management is a resource management system−not a single practice. In order to accomplish the goals of the resource management system, a variety of NRCS practices can be employed to maintain and enhance wildlife habitat.
Planning assistance may apply to two levels of wildlife habitat management. The first is for situations where wildlife production is the primary land use. The second applies to planning units where wildlife is a secondary land use.
Steps to use this guide
Identifies land use and client objective use the General Consideration section.
Using the Planning Consideration section, identified Animal Habitat Degradation _Inadequate Habitat for Fish and Wildlife resource concern. (Where, benchmark and planning level, target specie and others)
Use the Target specie in order to create, protect or enhance the habitat to guarantee their life cycles, providing air, food, cover, water, and spatial requirements. Not all elements may apply to every habitat type. The data included in Appendixes 1 to 10 include specific information regarding several requirements or characteristic for numerous species and conservation practices. This information we can use for develop recommendations or for conduct farm inventory.
GENERAL CONSIDERATIONS The following items must be considered when managing an area for upland wildlife:
Purpose of the project, including identification of the wildlife species or groups of species to be supported and the habitat needs that can be met on the managed property;
Surrounding landscape and its relationship to the project location; farms located adjacent or near State forest, secondary forest, federal forest, reserve, waterbody are requiring establish a buffer zone or transitional zone;
Site conditions such as soils, available water sources, water quality and quantity, and existing vegetation; all habitats will be planned and managed according to soil capabilities;
When recommend establish plants include documentation of the essential fish or wildlife species that will be benefited. Encourage plant diversity and native vegetation;
The positive and negative impacts that upland wildlife may have on the successful management of the site as well as on surrounding areas. Also consider the potential for attracting nuisance wildlife into an area;
The effects of management on plants and plant diversity, including the potential for invasion by undesirable and invasive species;
The effects of timing of management on wildlife;
The effects of management on non-targeted species, especially threatened and endangered species, and other species of concern; NRCS wildlife habitat planning assistance will not adversely impact a federally listed Threatened, Endangered, or Candidate species or its habitat. This also applies to State Species of Special Concern;
The potential use of ecological services in place of mechanical or chemical treatments to achieve management goals (e.g., services provided by grazers);
The effects of management actions on compliance with federal and state hunting regulations (e.g., baiting);
Other constraints such as recurring costs, availability of equipment, access to the site, regulatory or cost-share program requirements, social effects, and visual aspects such as compatibility with the natural landscape.
PLANNING CONSIDERATIONS: Planning Criteria
A planning criterion is a quantitative or qualitative method to assess the existing condition of the natural resources on a site to determine whether additional treatment is needed to address an Animal Habitat Degradation _Inadequate Habitat for Fish and Wildlife resource concern.
A planning consideration is a description of potential actions or activities that should be considered to help address an identified resource concern and/or to address unintended consequences of an action.
Screening Level_ Screening level criteria are defined, when appropriate, to identify sites with conditions that have little or no probability of needing additional treatment to address the specific resource concern. If the site meets the screening level criteria, then no other assessment is needed to document that planning criteria are met on this site.
Basic Assessment Level_ Basic assessment level criteria are used when a site does not meet screening level criteria, or when no screening level criteria are defined. Assessment levels are also used when formulating and evaluating alternatives.
Make sure that you document in the CPA-52 the resource concern: Animal Habitat Degradation _Inadequate Habitat for Fish and Wildlife. Maintain in the case file the planning tools and document to support the resource concern.
Use one of the following tools for the Basic Assessment level (as is necessary, select the tool according the resource concern as established in National and State Resource Concerns and Planning Criteria included in FOTG Section III):
a. Generalized Caribbean Wildlife Habitat Evaluation Guide (WHEG) according with the land use (crop, pastureland, forest, riparian)
b. Specie-specific wildlife habitat assessment tool
c. Stream Visual Assessment Protocol_2
Element 11: Barrier to movement
Element 12: Fish Habitat Complexity
Element 13: Aquatic invertebrate habitat
d. Document that
Conservation practice or management activities are in place does meet species or guild-specific habitat model thresholds or
Food cover or water are available in quality and extent to support habitat requirements for the species of Interest or
Connectivity of habitat components is adequate to support stable populations of targeted species.
Planning alternatives for wildlife will be based on a habitat appraisal. The Caribbean Area Wildlife Habitat Evaluation Guide (WHEG) will generally be used. These guides evaluate habitat for overall wildlife species diversity. When a habitat appraisal for a particular wildlife species is desired, consult the United States Department of Interior (USDI), Fish and Wildlife Service or local agency.
NOTE: Specific cost-sharing programs or other funding sources may dictate criteria in addition to, or more restrictive than, those specified in this guide.
All underlined items throughout the document are required to meet the Field Office Technical Guide (FOTG), Section IV, Practice Standard and Specification for Upland Wildlife Habitat Management (Code 645).
Wildlife Species Information
The NRCS conservationist’s primary wildlife management tool is the manipulation of vegetative habitat components. Use the information in this section as guidance in the identification and evaluation of the wildlife species requirement, habitats, distribution and for planning to improve or establish habitat.
A healthy river support aquatic live such as shrimps, crabs, snails, aquatic insects and insect larvae. In Puerto Rico most of the fish and shrimp river species have a complex life cycles, requiring them to spend a portion of their lives in the estuary or sea, they move downstream or upstream. Dams, water intakes, or river channelization affect most of these species preventing a free movement. Rivers have also been impacted either accidentally or deliberately by discharges that carry toxic substances or increase nutrients and organic load, thus decreasing available oxygen.
The high, steep streams are dominated by shrimp species and the Sirajo goby, a fish. Coastal plain streams are dominated by large shrimp, fish, and eels.
Consider conservation measures such as:
Maintaining minimum river flows,
Reducing obstructions to migration (dams, water intake) and
The ornithological fauna is one of the representations we have in Puerto Rico of the wildlife. Most bird species are shared with Virgin Island. Birds provide a service for the agricultural activities but not all the time is beneficial; sometimes the birds impact the agricultural yield production. The intensive agricultural also threaten birds. Appendix 2 include the habitat, nest and feeding description for endemic birds. Appendix 3 identify the nesting period. In order to planning to attract birds in the farm consider conservation measures such as:
Plant native trees.
Plant a variety of flowering trees and shrubs to provide year-round food
Pruning tree and shrub to promote healthier plants that tend to provide
more flowers and fruits which can be benefit to wildlife.
Promote agroforestry conservation practices
Provide wildlife scape ramp in the water though
Avoid using agricultural chemical in the bird habitat
Recommended buffers, hedgerows and similar plant structure
Reptiles work as biological control to several crops because they feeding with invertebrates and insect that are harmful. Also are important component in the food web for their diversity and abundance. Appendix 4 identified endemic reptiles for PR and USVI. The USVI has 16 native and in Puerto Rico there are51 are native species.
Diet consists mainly of terrestrial prey, such as insects.
Build brush pile (creating cover, providing additional structure to existing
habitat, enhancing prey availability).
Plant Native trees.
Avoid the introduction of exotic reptile.
Maintain structures using for shelter or protection such as ponds
Increase the area of habitat suitable for reptiles.
Rocks piled in a sunny spot will provide basking sites.
Consider planting shade-tolerant groundcovers under trees and leaving a thick layer of leaves to provide temperature shelter.
Stumps, logs, and rock piles in a shady spot can be valuable.
Maintain a mosaic of open habitats and scrub.
Maintain a diversity vegetation structure.
Avoid using agricultural chemical in the reptile habitat.
Amphibians are characterized by being dependent on water for reproduction. They have smooth semi-permeable skin, unlike the scaly skin of reptiles. With some exceptions, amphibians come together at a freshwater source to spawn and their aquatic larvae hatch out of gelatinous eggs to mature in the water.
They are important for agricultural activity. Example coquis represent a biological control of animals that harmful to crops. See Appendix 5 for information regarding several amphibians.
Diet consists mainly of insects, termites and small ants, spiders, and other invertebrates.
Build a rock pile under some shrubs,
Avoid to use agricultural chemical,
Enhance and maintain riparian forest buffer,
Reduce bank erosion,
Clean up trash in rivers, creek or guts,
Maintain ground terrestrial and leaf-litter,
Do not use pesticides: even those considered “safe” by industrial standard might have a potential toxic effects on amphibians,
Protect stream waterbody, ponds and guts.
The word pollinator bring to mind honey bees. However, pollinator may include also butterflies, moths, wasps, flies, beetles, ants, bats and even some birds.
A pollinator habitat enhancement include the improvement, restoration, enhancement, or expansion of flower-rich habitat that supports native and/or managed pollinators. This action provide pollen, nectar and nesting sites. Also is very important protect the pollinator form pesticides. For this reason when recommend a conservation practice focus on the fundamentals: forage, nest sites and protection from pesticide. Follow this tree rules 1) diversity; 2) variety of flowers (different size, color and shape) 3. Blooming entire year. Appendix 6 include detail information regarding bees and their relation with several crops Appendix 7 include several plants that will be recommended in order to provide habitat for support bees.
To establish bee pollinator habitat: Recommend native plant, flowering legumes, trees or forbs, in grazing lands consider long rest periods for allows for pollinators and plant recovery
Plant a variety of flowering forbs, legumes, trees and shrubs to provide year-round food for pollinator.
Locate pollinator habitat where chemical drift will not be a concern.
Avoid spraying herbicides or insecticides on field borders, filter strips, hedgerows and field windbreaks.
Select undisturbed areas, the best site for habitat area on the least erosive portion of the field, do not install pollinator habitat across areas of concentrated water flow
Implementing no-till farming to reduce disturbance of ground-nesting insects, especially for cropland adjacent to diverse herbaceous or woody cover.
Reduce or eliminate the use of insecticides. If possible select pesticides formulations that are less toxic to pollinators (for example, liquid forms are generally less toxic than granular powders, which are less noxious than dust) or break down faster. Avoid microencapsulated formulations, since they mimic pollen. Choose ground applications over aerial spraying. Time spray operations very early or late in the day when pollinators are less active.
Provide woody structure such as downed tree structures, make so an artificial nest site, using soil removed from drainage ditches can be piled to create potential bee ground-nesting habitat.

Bats are beneficial to agricultural activity. Bat species could provide pollination and pest management. Appendix 8 has a summary of bats species. The book Biodiversidad de Puerto Rico on chapter 4 identifies some species that provide food for bats: Higuillos (Pipersp.), Maria (Calophyllum calaba), Moca (Andira inermis), Mameyuelo (Colubrina arborescens), Maga (Thespesia grandiflora), Jagüey (Ficus sp.), Berenjena cimarrona (Solanum torvum), Yagrumo (Cecropia schreberiana), Ausubo (Manilkara bidentata), Palma de sierra (Prestoea montana)
Plant Species for Wildlife
Many tree and shrub species are excellent sources of food for wildlife. Proper selection of plant material can meet both the aesthetic needs of the land owner and the food and shelter needs of wildlife. When recommend to establish plants, include documentation of the essential fish or wildlife species that will be benefited.
Encourage plant diversity and native vegetation that occur in the area. It is extremely important to recommend native species. Native plants provide shelter and food for diversity of wildlife are adapted to local soil, rainfall and temperature conditions, and have developed natural defenses to many insects and diseases, require minimal irrigation, flourish without fertilizers, promotes local biological diversity, and are unlikely to become weedy.
Several fruit crop such as citrus, papaya, soursop and others are suitable food for wildlife, however an establishment of monoculture crop is not consider adequate manage for wildlife. Is necessary diversity ( Example:5 citrus trees, 5 soursop, 5 papayas or others), a multi-storied plant canopy of forbs, as well as juvenile and mature shrubs and trees, to provide a variety of above-ground habitat for birds and other wildlife, and below-ground habitat for burrowing animals and soil organisms.
Appendix 9 identifies some plant species to consider for wildlife habitat. This list does not include all options. The objective of the list is provide a guide to use for inventory the existing plants or select plants to establish, enhance or create habitat.
Application of conservation practices is generally considered to be beneficial for wildlife; other, practices can reduce wildlife food and cover when applied without consideration for wildlife habitat. The effect of conservation practice installation on wildlife habitat largely depends on practice selection, design and plant species used.
Planners that provide technical assistance to land users need to assess the impact of practice installation and explain to their clients the effect of a planned system of conservation practices on wildlife. When provided with this information, clients are able to make informed decisions about their land. See Appendix 10 for a summary the effect for a wildlife for each practice that have important benefit and those that have negative impact for a wildlife.
