Wildlife Management Terms - R

Rabbit: small, brown, furry,  herbivorous mammal which are prey for bobcats and foxes

Raccoon: four legged omnivorous mammal with brown fur, black face mask, a black and grey striped tail, and a humped back shape when walking. Primarily nocturnal (night feeding) eating reptile eggs  and fruits, along with scavenging

Ranavirus: genus of viruses that are highly infectious to amphibians and reptiles

Range: geographic area in which a species occurs 

Rattlesnake: carnivorous reptile and known as a pit viper. Sensory pits on their head detect heat emitted by their prey along with a triangular shaped head and rattles made of interlocking scales. They have hollow fangs that lie back in their mouths until needed, then are raised into a striking position when they stab their prey with the fangs and inject a toxic venom. They prey upon lizards, mice, rabbits, and other small mammals

Rattling: buck calling technique were horns are rattled together by a hunter simulating two buck fitting in hope of attracting the attention of a another buck and luring that buck into shooting range

Recruitment: addition of a number of young to an adult population of breeders, as in growth by reproduction

Recycle: use over again

Refugium (plural refugia): sheltering area in which animals an survive unfavorable conditions 

Regional linkage: connection of habitats, wildlife corridors, or greenways in a given region to facilitate wildlife migration, breeding, and dispersal 

Regulations: rules that establish when, where and how game species may be harvested as well as other permissions for interaction between the public and natural resources

Repellant: lotion or spray that is distasteful or that drives away insects or other animals

Reportable disease: disease that must be reported to federal, state, or local animal or human health officials when diagnosed

Reptile: class of vertebrates whose skin is dry, lacking in glands, and covered with scales. Claws are present and skull, limbs bones, vertebrae, muscles, and so forth are stronger and more advanced than those of amphibians. Egg fertilization is internal, there is no larval stage, and eggs have a protective, hard shell

Resident or Non-migratory Deer: deer that stay within their summer range during the winter

Restoration: returning a resource, ecosystem, or plant community to its original structure and composition of species 

Results chain: diagram that connects desired outcomes to strategies, by way of objectives and measurable goals

Reticulum: second chamber of a ruminant’s stomach (including deer) that holds partially chewed food

Riparian: pertaining to a river and the corridor adjoining it (i.e., the banks, floodplain); of, on, or relating to the banks of a natural course of water 

Riparian buffer: small area of permanent vegetation located adjacent to a body of water and designed to mitigate the effects of run-off containing pollutants, nutrients, and sediment while fostering a biodiverse natural community

Riparian zone: area influenced by the presence of a concentration of water. The banks of streams, lakes or marshes. The size of the area is influenced by hydrology

Roost: support or perch on which birds rest for the night

Roosting cover: overnight cover such as coniferous stands for wild turkey, shrubs for quail, dense pine saplings for doves, beaver ponds for wood ducks, or snags with cavities for woodpeckers, songbirds, squirrels, and other cavity users

Rub: limb or tree trunk a buck rubs or scrapes with its antlers to mark territory and display dominance

Ruff: projecting or conspicuously colored ring of feathers or hair around the neck of a bird or mammal

Rumen: first chamber of a deer's stomach that "washes" the browse a deer consumes with microorganisms designed to break down food

Ruminants: animals characteristically having a stomach divided into four compartments allowing them to consume a large amount of food quickly before seeking cover, then regurgitating and chewing a cud consisting of the partially digested food

Runoff: nutrient-loaded water that flows across land, picking up pollutants and excess chemicals, and eventually enters a body of water
