18 PROCEEDINGS OF THE FIFTH MOUNTAIN LION WORKSHOP<br />

1935 to 1995.<br />

input into <strong>the</strong> policies and procedures <strong>of</strong> <strong>the</strong> plan. The<br />

policies are <strong>the</strong> foundation <strong>of</strong> <strong>the</strong> plan that are to guide<br />

NDOW in <strong>the</strong> management <strong>of</strong> <strong>the</strong> species. The following<br />

include <strong>the</strong> resulting policy concepts: conservation <strong>of</strong> <strong>the</strong><br />

species; control <strong>of</strong> <strong>mountain</strong> <strong>lion</strong>s damaging property; control<br />

<strong>lion</strong>s threatening human, health, and safety; maintain moderate<br />

harvest through <strong>lion</strong> hunting with <strong>the</strong> use <strong>of</strong> hounds; control<br />

<strong>of</strong> <strong>lion</strong>s when <strong>the</strong>y are shown to be a limiting factor to a<br />

localized wildlife population; encourage <strong>lion</strong> research;<br />

emphasize public education on <strong>mountain</strong> <strong>lion</strong>s.<br />

Currently, <strong>the</strong> management program involves<br />

depredation control, sport harvest, and data collection. Under<br />

current procedures, a landowner claiming <strong>the</strong> loss <strong>of</strong> livestock<br />

may contact <strong>the</strong> Division <strong>of</strong> Wildlife or <strong>the</strong> U.S. Department<br />

<strong>of</strong> Agriculture, Animal and Plant Health Inspection Service,<br />

Animal Damage Control (ADC) to investigate and confirm<br />

property loss due to <strong>mountain</strong> <strong>lion</strong>. If confirmed, ADC or <strong>the</strong><br />

landowner under a depredation permit, may pursue and kill <strong>the</strong><br />

<strong>of</strong>fending <strong>mountain</strong> <strong>lion</strong>. Most <strong>of</strong>ten when a domestic pet is<br />

taken by a <strong>mountain</strong> <strong>lion</strong>, deterrent methods are suggested to<br />

prevent fur<strong>the</strong>r loss.<br />

In 1994 and 1995 ADC received a total <strong>of</strong> 149 and<br />

104 calls respectively, regarding <strong>lion</strong> predation on livestock<br />

(C. L. Johnson <strong>of</strong> ADC, pers. comm.). NDOW received<br />

approximately 20 additional calls in 1994 and 28 additional<br />

calls in 1995, primarily on <strong>lion</strong> predation to pets and concerns<br />

for human safety. A general trend <strong>of</strong> increasing depredation<br />

complaints on <strong>mountain</strong> <strong>lion</strong>s occurred from <strong>the</strong> late 1980's<br />

through 1994. In 1995 <strong>the</strong>re was a drop in complaints,<br />

especially from <strong>the</strong> ranching community regarding<br />

depredation on livestock. From 1990 to 1995, an average <strong>of</strong><br />

47 <strong>mountain</strong> <strong>lion</strong>s were killed annually in response to<br />

depredation, primarily involving livestock.<br />

Periodically, <strong>mountain</strong> <strong>lion</strong>s are involved in<br />

encounters with humans in Nevada. Over <strong>the</strong> last five years,<br />

<strong>the</strong>re have been less than ten reported cases <strong>of</strong> <strong>lion</strong>s attacking<br />

humans in Nevada. Only one case involved a <strong>lion</strong> making<br />

physical contact, where a woman received minor injuries,<br />

before <strong>the</strong> <strong>lion</strong> was driven away by two men. Due to<br />

incomplete records and reporting by <strong>the</strong> public, no comparison<br />

can be made <strong>of</strong> <strong>the</strong> number <strong>of</strong> <strong>lion</strong> encounters in Nevada<br />

through time. To NDOW's knowledge, <strong>the</strong> only known<br />

human fatality from a <strong>lion</strong> attack was a young boy back in<br />

1880. Future emphasis will be placed in providing<br />

information to <strong>the</strong> public on how to reduce <strong>the</strong> risk <strong>of</strong> having<br />

a dangerous encounter with a <strong>mountain</strong> <strong>lion</strong>, improve<br />

documentation <strong>of</strong> <strong>lion</strong> encounters, and provide guidelines to<br />

NDOW employees in responding to <strong>lion</strong>/human encounters.<br />

Currently, <strong>mountain</strong> <strong>lion</strong>s are harvested in Nevada<br />

under a sport harvest objective system, where unlimited tags<br />

are sold. The statewide average harvest objective for <strong>the</strong> last<br />

three years (1993-1995) for all management units has been<br />

239 <strong>mountain</strong> <strong>lion</strong>s. An average <strong>of</strong> 161 <strong>mountain</strong> <strong>lion</strong>s were<br />

taken by sport hunters during each <strong>of</strong> <strong>the</strong> previous three<br />

hunting seasons. Hunting seasons typically run from October<br />

1 through April 30. Mountain <strong>lion</strong> tag holders are responsible<br />

for calling a toll-free telephone number during <strong>the</strong> hunting<br />

season to determine whe<strong>the</strong>r a particular management unit(s)<br />

is open or closed (when <strong>the</strong> harvest objective was met).<br />

NDOW spends approximately $100,000 annually on<br />

<strong>the</strong> management <strong>of</strong> <strong>mountain</strong> <strong>lion</strong>s. Funds are primarily spent<br />

by biologists and game wardens during mandatory check-ins<br />

<strong>of</strong> harvested <strong>mountain</strong> <strong>lion</strong>s and development <strong>of</strong> federal aid<br />

reports. Funding may be pursued to increase educational<br />

efforts regarding <strong>mountain</strong> <strong>lion</strong> public safety and general<br />

ecology. Opportunities to collect additional information on<br />

<strong>mountain</strong> <strong>lion</strong> demography and hunting pressure may also be<br />

assessed. ADC, in <strong>the</strong> pursuit <strong>of</strong> depredating <strong>mountain</strong> <strong>lion</strong>s,<br />

expended approximately $41,000 in 1994 and $38,000 in<br />

1995.<br />

Currently, no formal research on <strong>mountain</strong> <strong>lion</strong>s is<br />

being conducted ei<strong>the</strong>r by <strong>the</strong> Division <strong>of</strong> Wildlife or any<br />

research organization in Nevada. The most recent research<br />

activity involving <strong>mountain</strong> <strong>lion</strong>s was a study focused on wild<br />

horse recruitment in relation to <strong>mountain</strong> <strong>lion</strong> predation. The<br />

study was located along <strong>the</strong> border <strong>of</strong> California and Nevada.<br />

Much <strong>of</strong> what is known about <strong>mountain</strong> <strong>lion</strong>s in<br />

Nevada is based on a 10-year study that was completed in<br />

1982, "The <strong>mountain</strong> <strong>lion</strong> in Nevada", Ashman et al. 1983.<br />

NDOW encourages future research that may provide a better<br />

understanding <strong>of</strong> <strong>lion</strong> demography and predator-prey<br />

relationships that can be directly applied to management <strong>of</strong><br />

<strong>lion</strong> populations.<br />
