393 Components of Effective Wildlife Management gt Take into account Target species or Community Welfare factors and limiting factors Human and societal values or impacts 0 Think back to Gene Decker s lecture and important values he discussed 393 Carrying capacity k gt Social carrying capacityhuman ideals a little bit below the natural threshold Might not want wildlife destroying gardens and land used by people 0 Thus limits carrying capacity due to human intervention Direct management Concern on what to do with wildlife lncreasedecreasemaintain Local Colorado examples Moose and chukar introductions via translocation to new areas Bighorn sheep and mule deer culling for disease culling is the deliberate human intention to go directly manage a population by killing some of the species 0 Plains sharptail grouse reintroductions to native habitat Indirect management Habitat alteration Prey manipulation Education to promote conservation ethic Local Colorado examples 0 Creating wetlands for waterfowl Stabilizing islands for breeding pelicans Controlled burn for bighorn sheep forage Nest platforms for osprey CRP for plains sharptailed grouse Categories of Wildlife Gameharvested o Managed through licensing and reporting of hunts Nongamenot harvested Game Big game mountain lions bears ungulates Hunting is polarizing and dynamic Very opinion based Most valuable species in CO Elklargest herd in North America is in CO whoop Deer is the big game species most harvested nationwide White tailed deer O O 90 90 Usually run with tail up Rack is like a stick with prongs gt Mule deer Usually run with tail down and white booty patch Rack has a fork Big game complexities gt Over populated in areas outside of hunting gt Social k exceeded gt Overbrowsedamage gt DiseaseCWD gt HumanWL con ict Why do we allow predator hunts gt Livestock loss gt Human safety gt Impacts to other big game gt Generates trophy Game 2 gt Turkey Smallish big game or biggest small game Hunting regulation structure like big game mammals in Colorado Small game gt Certain mammals birds and reptiles gt Larger bag and possession limits Usually are r selected species 0 Fast recovery rates Furbearers gt Controversial Types of traps o How humane Economic value 0 How much real economic bene t Native people 0 Effects on people not just the animals change the structure of the environment gt Beavers gt Dams kills trees reroutes water provides fish habitat Reintroductions with furbearers gt Some traditional furbearers in other states are protected in Colorado gt Bene t of the animalsfor ecological diversity Think about WHY diversity is actually important Lynx has big ear tufts black tip tail and HUGE feet Includes B upland game birds gt Sage grouse gt Complexities Many species are favored by a high diversity of habitats and subsequent creation of edge but not all Aldo leopold quotsmall game is the phenomenon of edgesquot mportant guy in wildlife conservation get used to this name Quail Covey habitat and edge like mixed cover and diversity in a small area for the home territory 0 Important to Agricultural and Conservation Reserve Program 0 Quail like the corner region of all the land plots Pheasants gt Not intelligent gt Direct management with stocking Put a lot of the birds in each area Migratory Game birds gt Migratory Bird Treaty Act gt Federal regulationinternational relations One place can affect all others because the birds moveduh gt Waterfowl gt Nonwebbed migratory game birds gt Sandhill cranes Can hunt in CO with state and federal permit Like sand bars Nesting Easy food source predators gt Waterfowl migration routes are called yways gt Loss of wetland habitat Mourning dove gt Upland small game species gt Nonhunted depending on where you live Prairie dogs gt Can control on private land as a nuisance but need small game license on public land gt 98 decline led to proposal to list as federally threatened gt USFWS denied protection gt Ecosystem engineer and keystone speciesdisproportional affect on structure on food webs Non game gt Endangered species gt Watchable wildlife Management Approaches gt Maximize species richness of species Pros managing for many species promotes watchable wildlife Cons nonnatives included gt Maximize Ecosystembiome function Pros protecting potential for diversity now and future Cons unrealistic Not enough time Common Management Errors gt gt gt gt gt Small scale implementation and understanding Open systems Missing life history and ecology Oversimpli cation No evaluation of management impacts Densitydependent factors gt gt gt lntraspeci c competition for resources predation disease etc logistic growth model based on operation of Density Dependent factors Densityindependent of population density gt gt Nothing to do with how big the population is Weather accidents etc quotrselectedquot life history strategies gt gt gt gt adaptations for rapid population growth reproduce rapidly highly mortality rapid turnover of generations good dispersal little effort in young many offspring poor competitors better adapted for unstabletransient habitat conditions Earlymid succession pioneers a lot of uctuations in populations quotK selectedquot life histories gt gt gt competition for resources is intense good competitors low reproductive rates few offspring more effort into young feeding defense from predators adapted for stable habitat climax communities Wildlife Tracking gt gt gt gt What are we interested in learning What techniques and tools do we have to observe catch mark or follow animals lnvasive vs noninvasive What do we want to learn Harvest rate Population size Birthrates and mortality 0 Age and growth o Study lifetime of a marked animal is difficult gt R selected species are much easier o Tooth wear gt Invasive or non invasive Document foodhabitat type Noninvasive scat and pellet analysis behavior observation Invasive stomach analysis live or dead Movementdispersalhome range Catching and handling wildlife 0 Safety 0 Process quickly quietly and carefully Reduces drugs needed struggle and injury 0 Trapping netting darting Noninvasive quotcapturequot 0 Remote cameras 0 Track plates 0 Hair snares 0 Scat Examples of traps used for each animal would be important to study
