Unit Map Set Up Unit name: Wildlife management Unit Essential Question: How can we manage wildlife to provide the best biodiversity?
Lesson Essential Question What are the different species of wildlife?
History Mammals, birds, and fish enabled the early pioneers to survive. Meat=food skins=shelter and clothing Oil from animal fat=kept firearms usable and light in cabins
History Species of wildlife, such as bears and cougars were killed because they were a ‘threat’
Niche Niche- Role an organism or population plays within it community or ecosystem Why is this important?
Species- Rare Rare- populations are very small and usually in one area EX: snowy owl (Harry potter), blue- footed boobies (Galapagos islands), clouded leopard (Asia), woolly mammoth (Siberia), star-nosed mole (eastern North America)
Activity: Research Extinct animals. Pick a species, research how they became extinct. Are there any regulations that came out after they became extinct?
Wildlife Management Habitat and Population Control
Warm-up What was special about your extinct species?
Lesson Essential Question How is population controlled?
Habitat Requirements for Wildlife Food: Herbivores (plant eaters) Carnivores (meat eaters) Insectivores (insect eaters) Frugivores (fruit eaters) Omnivores (eat many different foods) Spermivores (seed eaters)
Habitat Requirements for Wildlife Food: Euryphagus- consumes great variety of food Stenophagus- animal that eats a specialized diet
Habitat Requirements for Wildlife Cover: Animals must have a place to protect them from weather conditions. EX: fences, trees, water, furrow, etc.
Habitat Requirements for Wildlife Water: Most important requirement. Bodies of most animals consist of 60-80% water Water important for blood composition, temperature regulation, and nutrient transport No water= no wildlife
Habitat Requirements for Wildlife Home Range- area which game travels Territory- area an animal will defend even to death Home range will overlap
Population Control Every animal reproduces. Why aren’t we over run with mice?
Population Control All species need shelter, food, water and safety area= habitat Limiting factors- something that will limit the species. Food, water, sunlight, predators, disease or something else.
Population Control Carrying Capacity- no single species can ever reproduce without limit.
Population Control Logistic curve- shows how population of an organism in a given habitat grows at an increasing rate until limiting factors start to slow and eventually stop the population increase altogether.
Population Control Methods Hunting Re-Introduce Natural Predators Controlled Burns Prevent Human Feeding of Animal High Fencing around crops and Plants
Game Management Game Refuges- land set aside for the protection of wildlife species. Provides basics for survival (no hunters) No protection once leave refuge No protection from natural predators
Game Management Habitat Development – development and improvement of food, water, and shelter for wildlife Fences for Cover Woodland Management- allow livestock to graze (decrease in game) or not graze (increase in game)
Game Management Coordination with other resources Work with farms to leave a row or two of crops for wildlife feed
Game Management Hunting Regulations Hunting-killing of game for food or pleasure Bag limits- restrict the # of animals one can take per day, season, etc.
Game Management Hunting Regulations Bison crisis created solutions to over hunting Hunting controlled on public and private lands Hunting seasons and closed seasons change each year in accordance to population size.
Game Management Predator Control- based on 2 beliefs Medium sized and large predators can be dangerous to people Predators can be a threat to domestic livestock and wild game
Game Management Beneficial Predators 1. Control on prey species by # of predators controlled 2. Predators feel on pests (rats and mice)
Game Management Beneficial Predators 3. Predators control practices keep species in a healthier condition 4. Predators help maintain improved game by killing weak and handicapped individuals
Game Management Artificial Stocking- stocking of game natural to the area or the introduction of species new to the area New species- to introduce new or additional species to an area or to supply predators for population problem. Dangerous
Game Management Artificial Stocking 2 principles carefully examined: Wildlife biologist must examine the desired population density (# of game animals in a defined area) Estimated Carrying Capacity
Game Management Artificial Stocking Estimated Carrying Capacity Population increase- environmental problems Too much game= starvation, unhealthy animals, disease problems
Game Management Individual Landowner Game Management. Reading Create a drawing of what you would include using hand out and book. Write a description of what you included and why.
