We will discuss: Our Goals and Objectives Current Situation and Condition of Camp Sacajawea Desired Future Conditions Ecosystem Needs Assessment process used Recommended feasible management actions Effects and Benefit Cost analysis of actions
4
Emphasis Primary -Wildlife Habitat Unit Values Secondary -Quality sawlog removal for fiber and firewood sales
5
Goals Increase overall mean Habitat Unit Values in Camp Sacajawea Remove timber for income through firewood and fiber sales
6
Objectives To increase mean Habitat Unit Values in Camp Sacajawea by 25% in the next 20 years To remove 25% of AGS, UGS, and Cull timber exceeding 20 in. DBH for saw- log sales by 2020 To remove majority of Ironwood trees in Camp Sacajawea
7
Current Conditions at Camp Sacajawea Camp is approximately 400 acres in size located at NE ¼, Sec 2, R274W, T84N, 5PM Camp is located on the Des Moines river valley Only 170 acres on west side of camp were studied
8
Current Conditions (continued) Terrain of camp is very steep and hilly Soil – Hayden – well drained and moderately permeable found on slopes and ridges Oak forest that has been overrun by Ironwood trees. Very low oak regeneration.
9
Current Conditions (continued) Habitat Unit Values -Deer and Turkey – 5.5 -Squirrel – 5.5 Basal Area -Approximately 81.6 sq.ft/Acre -Ironwood=18% or 15 sq.ft/Acre
10
Desired Future Conditions Habitat Unit Values -Deer and Turkey – 7.0 -Squirrel – 6.5 An increase of 25% of previous HUV’s Low % of ironwood population High % of oak regeneration and existing oaks
11
Ecosystem Needs Assessment Identify issues, concerns, and opportunities Develop decision criteria based on goals and objectives developed from previous step Collect all data and information needed to create feasible actions Assess current conditions
12
Step I – Issues, Concerns, and Opportunities Mid range Habitat Unit Values where high values are possible High number of Ironwood trees causing low HUV’s Many AGS, UGS, and Cull trees exceeding 20 in. DBH
13
Step II – Decision Criteria First Consider Assumptions - Capabilities of the ecosystem are limited - Ethical Standards will be applied - Risk and Uncertainty will exist Criteria and principles - Humans are considered part of the ecosystem
14
Criteria and principles (continued) - Human actions will cause positive effects to the productivity, diversity, and resiliency - Ethical decisions will be made - Actions will satisfy camp manager uses and benefit the ecosystem
15
Step III – Collect needed data Systematic sampling was used with regard to finding saw timber and wildlife values Approximately 50 points were sampled throughout the forest and projected onto a larger scale Considerations used for saw timber - Oak regeneration - Soil samples - Non-oak species
16
Data Collecting (continued) Process of evaluation of wildlife habitat based on “A Handbook for Habitat Evaluation Procedures” provided by the U.S. Department of Interior Wildlife Considerations For Tree Squirrels - Tree Size and Canopy cover
17
Wildlife considerations for tree squirrels (continued) Food diversity Shrubs and Herbs available Tree Cavities Openings in Canopy Diversity of non-preferred plant species
18
Wildlife Considerations for forest game (deer and turkey) Tree Size and Canopy Closure Food Diversity Browse Availability Vegetative Cover Openings in Canopy Diversity of Non-preferred plant species
19
Step IV - Assessment of Current conditions
20
Feasible Management Actions Based on assumptions and decision criteria Each action has pros and cons with regard to desired future conditions of saw-timber and wildlife habitat Final decision must be made by the managers of Camp. These are simply recommendations
21
Feasible Management Actions Removal of all Ironwoods Selective cutting of trees over 20 in. diameter Actions such as food plots, maintaining current conditions, and clear-cuts were considered but deemed non-feasible
