Pollution 5 l Pollution has many different effects on wildlife. l It is common to direct the number of different species impacted by the pollutant and the kinds of organisms that are present when assessing pollution.
Biological Magnification l l Pollutants are measured through biological magnification. Biological magnification is the process in the food chain where pollutants increase to a concentrated level. 6
Direct Effects l Pollution can have direct effects on wildlife. l Direct effects are those that are initially present in the species. 7 l Disease l Physical impairements l Infertility
Indirect Effects l Pollution can have indirect effects on wildlife. l Indirect effects of pollution on wildlife includes habitat that fails in its support of the species. 8 l Damaged habitat – inadequate shelter l Unable to obtain the needed nutrients
Natural Events l Some pollution that damages a habitat is a result of the natural events on the earth’s surface. l l l 9 Volcanoes Climate and weather patterns Lack of precipitation
How are Habitats Destroyed ? 10 l Cutting timber (logging) l Clearing land – use of heavy equipment l Storing waste - lack of recycling l Mining l Animals l Crop production
Natural Conservation Policies l 11 The National Park Service was established in 1916. l 330 protected areas such as Yosemite, Sequoia, the Great Smoky Mountains, Carlsbad Caverns l Oversees monuments and parkways
Natural Conservation Policies l 12 The Lacey Act was passed in 1900 as the Game Bird and Wild Bird Preservation Act. l Regulates the shipment of illegally killed animals and international trade of protected wildlife l The Migratory Bird Hunting Stamp Act (1934)
Natural Conservation Policies l 13 Pittman-Robertson Act - passed in 1937 l Placed an excise tax on all hunting equipment and ammunition l Money collected by the federal government is made available to the states on a matching fund basis.
Natural Conservation Policies l 14 A Wildlife Refuge System was organized in 1966 as part of the U. S. Fish and Wildlife Service. l More than 400 refuges that contain vast land areas in the US l The National Park Service and the Fish and Wildlife Service are part of the U. S. Dept of the Interior.
Natural Conservation Policies l 15 The U. S. Forest Service has 156 national forests throughout the nation. l Originally set up to protect timber and water as part of the federal forest conservation policy of 1891 l Estimated that the national forests contain 60% of the nation’s wildlife l Manages 191 million acres of forest and grass land
Wildlife Conservation Banding l Bird banding is used to provide information on migration routes and the numbers of birds that survive each year. l Banding is placing a band around the leg of a bird to identify it for study. l l l 16 Captured in traps or with rocket-propelled nets Bands attach to their legs before they are released Ensures bird populations are maintained
Wildlife Conservation Land Management l 17 Land Management is used to provide a secure habitat for species that require protected areas. l Most common in wildlife management areas or refuges l Maintained in a way that supports the specified species
Wildlife Conservation Trapping & Transplanting l 18 Trapping and transplanting are processes used to boost low populations or to develop a new population. l Trapping animals in highly populated areas and moving them to another suitable location l The animals are expected to reproduce and increase in population numbers.
Wildlife Conservation Wildlife Population Survey l 19 A wildlife population survey is counting the number of wildlife in an area. l Gives information about the relative abundance of a particular species l Allows biologists to set up management programs l Birds, alligators, and deer are counted in order to be able to make laws and hunting regulations.
Wildlife Conservation Vegetation Survey l 20 A vegetation survey determines the kinds and amounts of vegetation present in important wildlife areas. l To make certain the plants needed by wildlife are in adequate supply l To make sure there is no danger of the plant supply being depleted
Habitat Management Plan l 21 A habitat management plan is a written document describing the needs of an area to improve a habitat for a featured species and specifies how and when the work will be done. l Often require several years to implement l Without a good plan money and time may be wasted on projects that do not give good results
22
Habitat Management Plan Step 1 l 23 Animal inventory - Make a list of the animal wildlife in the area, including: l A short description of the species l The size of the population
Habitat Management Plan Step 2 l 24 Plant inventory - Make a list of the plant species and the number found. l Animals depend on these plants for food l A note should also be made where the plant materials are typically found.
Habitat Management Plan Step 3 l 25 An analysis should be made on the plant and animal inventories. l A comparison should be made on what is found with the climate and other conditions that species need to flourish. l Costs and benefits should be estimated l Assess what can be done quickly and at a low cost
Habitat Management Plan Step 4 l 26 A map should be prepared of the area selected for improvement. l Show streams, trees, and elevation changes l Improvement locations should be marked on the map.
27
Habitat Management Plan Step 5 l 28 A plan should be written that lists the goals to be achieved and how they will be done. l Should be indicated as short-term or long-term l Describe how and when the projects will be carried out
Habitat Management Plan Step 6 l 29 A regular assessment on the progress and the results should be made of the habitat improvement. l Make the needed changes l Use experts assistance if necessary
SAMPLE PLAN 30
Small Area Management Practices l 31 Woodland is land that has some covering of trees. l Often has a variety of stages of maturity and mixed species. l Forests that have the same woodland characteristics with uniform species at the same stage of growth are called tree farms.
Small Area Management Practices l 32 A woodland area on a farm may be referred to as a woodlot. l These woodlots lack uniformity of species and maturity. l Many herbivores in the forest that feed on mast, browse, and forage. l Mast is nuts, seeds, and fruit from trees and shrubs.
Small Area Management Practices l 33 Dead wood is used for nesting, finding food, and as a perch. l Some species prefer dead wood such as snags. A snag is a standing dead tree. (woodpeckers, owls) l Downed trees make logs on the ground are used by snakes, salamanders, chipmunks, and mice.
Small Area Management Practices l The amount of dead wood in an area can be increased by causing the death of live trees or leaving old trees to fall naturally. l Girdling can be used to kill a tree. l Girdling is the cutting a small trench around the circumference of a tree trunk. 34
Small Area Management Practices l 35 Brush piles attract fox, skunks, rabbits, snakes and many other species. l Made of twigs, logs, limbs, stones, other materials. l Can be created artificially to serve as habitats for many animals
Small Area Management Practices l A shelterbelt (or windbreak) is a row or several parallel rows of trees and shrubs planted to reduce wild currents and drifting snow in northern climates. l 36 Shelterbelts and food plots are helpful in attracting wildlife.
Small Area Management Practices l 37 Grasslands are important for many species of animals. l Wolves, prairie chickens, meadowlarks, badgers l Require moisture than desert land are often used for livestock production. l Cutting once a year should control the growth of scrub trees. l Examples: red clover, alfalfa, wild oats, switch grass
