    Eastern Cottontail Rabbits (Sylvilagus Floridanus)

    Publication WSFNR-20-58A July 2020 Managing Wildlife Damage: Eastern Cottontail Rabbits (Sylvilagus floridanus) Joseph Brown, UGA Warnell School of Forestry & Natural Resources Michael T. Mengak, UGA Warnell School of Forestry & Natural Resources INTRODUCTION Eastern cottontail rabbits (Sylvilagus floridanus) are found across the eastern United States, southern Canada, eastern Mexico, Central America and portions of South America (Figure 1). Cottontail rabbits are a sought-after game species by small game hunters. Many people enjoy seeing them around their yards and neighborhoods. Rabbits are well accepted by humans when their numbers are managed correctly. However, they can inflict damage across a range of habitats from rural farms to suburban lawns. They often damage flowers, vegetable gardens, and landscape trees and shrubs. TAXONOMY Class Mammalia Order Lagomorpha Family Leporidae Genus - Sylvilagus Species – floridanus Common Name - Eastern cottontail rabbit There are 11 genera and 54 species in Leporidae which includes hares and rabbits. Six species of cottontail rabbits are found in the genus Sylvilagus. The scientific name, Sylvilagus floridanus, means forest hare of Florida. Figure 1: Current eastern cottontail STATUS distribution across North and Central America. In Georgia, we have 4 native species of rabbits. The swamp rabbit (Sylvilagus aquaticus), Appalachian cottontail (S. obscurus), marsh rabbit (S. palustris), and eastern cottontail (S. floridanus). The eastern cottontail (Figure 2) is the most abundant and ranges across the entire state. The Appalachian cottontail is the rarest rabbit and inhabits the start of the Appalachian mountain chain in North Georgia. It is on the Georgia Protected Wildlife list. The swamp rabbit is the largest of the four and inhabits swamps in the Piedmont region of Georgia.

LOPEZ, Department of Wildlife and Fisheries Sciences, Texas A&M University, College Station, TX 77843-2258, USA ABSTRACT We used nucleotide sequence data from a mitochondrial DNA fragment to characterize variation within the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri). We observed 5 unique mitochondrial haplotypes across different sampling sites in the Lower Florida Keys, USA. Based on the frequency of these haplotypes at different geographic locations and relationships among haplotypes, we observed 2 distinct clades or groups of sampling sites (western and eastern clades). These 2 groups showed low levels of gene flow. Regardless of their origin, marsh rabbits from the Lower Florida Keys can be separated into 2 genetically distinct management units, which should be considered prior to implementation of translocations as a means of offsetting recent population declines.

Black-tailed jackrabbit (Lepus californicus) Fig. 2. Desert cottontail rabbit (Sylvilagus audobonii) Fig. 3. Brush rabbit (S. bachmani) Introduction: Three rabbits are common to California: the black-tailed jackrabbit, the cottontail, and the brush rabbit. Of these, the jackrabbit is the most destructive because of its greater size and occurrence in agricultural areas. Cottontails are common pests in landscaped areas. Hereinafter ‘rabbits’ shall refer to all three species unless distinguished otherwise. Rabbits can be destructive and eat a wide variety of plants, grasses, grains, alfalfa, vegetables, fruit trees, vines, and many ornamentals. They also cause damage to plastic irrigation through their gnawing activities. Identification: The black-tailed jackrabbit (Fig. 1) is about the size of a house cat, 17 to 22 inches long. It has long ears, short front legs, and long hind legs. They populate open or semi open lands in valleys and foothills. Desert cottontail (Fig. 2) and brush rabbits (Fig. 3) are smaller (14.5 to 15.5, and 12.0 to 14.5 inches in length, respectively) and have shorter ears. Brush rabbits can be distinguished from cottontails by their smaller, inconspicuous tail and uniformly colored ears that lack a black tip. They inhabit brushy areas where cover is dense; landscaped areas provide excellent habitat. They can also be found beneath junipers and other large, low-growing evergreen shrubs. 262 VERTEBRATE PEST CONTROL HANDBOOK - MAMMALS Legal Status: Black-tailed jackrabbits, desert cottontails, and brush rabbits are classed as nongame animals in most states, but are considered game mammals by the California Fish and Game Code.
  • Appendix Lagomorph Species: Geographical Distribution and Conservation Status

    Appendix Lagomorph Species: Geographical Distribution and Conservation Status

    Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaça˜o em Biodiversidade e Recursos Genéticos and Faculdade de Ciˆencias, Universidade do Porto, Campus Agrário de Vaira˜o 4485-661 – Vaira˜o, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str.

  • Desert Cottontails

    Desert Cottontails

    Name: ____________________________________________ Desert Cottontails The desert cottontail is a type of rabbit that lives in the dry, dusty areas of New Mexico, Arizona, and Western Texas. They can also live as far north as Montana and as far west as California. This type of cottontail is similar to other rabbit species because it has an easily-noticed white fluffy tail, but it has larger ears that usually stand straight up. They have the potential to weigh up to 3.3 pounds (1. 5 kg) and grow to 20 inches (51 cm) in length. Desert cottontails tend to be most active during the morning and late afternoon hours. During the day they avoid the hot desert sun, and seek shelter to keep themselves cool. Desert cottontails will eat almost any type of plant, and sometimes they’ll munch on small bugs as well. Because the desert plants they eat usually contain moisture, desert cottontails rarely need to drink water. The cottontail has many predators, including bobcats, mountain lions, owls, eagles, rattlesnakes, and coyotes. Sometimes they are able to outsmart the large predators by running very fast and diving into small holes where bigger animals cannot go. They usually run in a zigzag pattern so they’re harder to catch. Cottontails are one of the few species of rabbits that are also able to climb trees when they’re trying to escape a predator. When she is ready to have babies, a female cottontail will make a nest of grass and fur. They can have as many as ten baby cottontails at one time! And sometimes they can have four litters in a single year.
