GoalsB. 10 dominant themesCurrent LectureI. Natural Heritage Program (Colorado): - Part of CSU through Warner College of Natural Resources. service, research, self-funded, and part of NatureServe Network- Objective / science based, support conservation, management, and developmentwith science info and data, five teams with are botany, ecology, zoology, conservation, sustainability. - tracks location and status of rare, native and endangered species which they are the only program that does so VIII. Why there are so many species and ecosystems in CO? - huge topographic variation- complex topography & geology- adaptive radiation- disjuncts and peripheral species- relictual speciesA. Work to answer 5 questions; - What species & ecosystems exist? - Which are at risk or otherwise significance? - Where precisely found? - How are they doing at those locations?- What are the most important and urgent places to protect? B. Why we answer those questions: - Regulations: endangered species act, national environmental policy act, sikes acts, clean water act, objectives of NGOs: natural conservancy, aldn trusts, research, education, C. Way answers those questions: build data and share data on the locations, status, andconservation priority of rare and imperiled species. IX. Nature serve ranking systems: - global ranks - show the degree of rarity on the global scale- state rank - show the degree of rarity on the state scale based on its critically imperiled, imperiled, vulnerable to extirpation or extinction, widespread, abundant and secure. - Ranks used on number of occurrences ….- Jefferson county biological inventory: inventoried in 1992, NCHO identified 84 high quality natural areas, 32 of these supported species of concern, 65% of the areas ID in 1992 are now conserved…, in 2009 NCHO began another inventory of Jefferson county- Data comes from: country surveys, other CNHP field projects, museum/herbarium records, scientists, citizen scientist, EPA;X. What are ecological systems- Complexes of plan and or animal communities that: occur together on the landscapeXI. Ways that CNHP can help students: - internships for academic credit- work study and hourly employment- Americorops education awards- networking & research opportunities- professional internship program- service learning- on the job experience/resume building- leadership and training- Current student opportunities at CNHP: wetland herbarium development, field projects starting this summer, what are you interest? (potential independent study, honors thesis research)XII. Biome- Large, relatively distinct ecological systems characterized by particular climate, soil, plants, and animals. - What affects the distribution of major biomes? - Climate – temperature & precipitation (triangle warm to cold then dry to wet)- What happens on mountains? Vertical zonation, - The wildlife managers toolbox: foundations – knowledge, scientific method, techniques/populations, ecosystem management (EM), succession and disturbance, system thinking, spread the word of education and outreach. - IclickerQ: effective ecosystem management focuses primarily on ecological structure, function and biodiversity? True - Effective EM focuses primarily on the human dimensions relate to functioning ecosystems. - Effective EM includes both ecological and human components. - It is not feasible to manage ecosystems effectively. - Management considerations: tamarisk (introduces for bank stabilization, greatly increased song bird pops, appearance of peregrine falcon, encroaching & neg. impacting the cottonwoods), nike perch (competition for fishing and food source, reduction in native fish tilapia graze on algae, create O2, depleted zone, poor cover habitat for nativefish, native culture depended on air drying tilapia, built fires to cook it which equal erosions and deforestation, commercial fishing- EM: hard to define: what are the components? = ecological, social/political, economicXIII. Edward grumbine’s ecosystem managementJ. Goals1. Viable populations2. Native ecosystem types 3. Ecological processes maintained – enough to maintain and evolve 5. Accommodate human use and occupancy. B. 10 dominant themes1. Hierarchical context 2. Ecological boundaries “scale selected and the boundaries used for an ecosystem depend on the problems or question being addressed “present s. desired conditions” 3. Ecological integrity 4. Data collection 5. Monitoring 6. Adaptive management 7. Interagency cooperation 8. Organizational change 9. Humans embedded in nature 10.
