1 Revisiting the CFIRP : Assessing long ‐ term ecological value and characteristics of snags created for wildlife J.W. Rivers & J. Hagar

2 Snags provide critical habitat! Huge contribution to biodiversity > ¼ of forest species use dead wood Woodpeckers create habitat

3

4 College of Forestry Integrated Research Project Large ‐ scale, long ‐ term manipulative experiment Tests effects of alternative harvest methods 3 treatments: clear-cut, patch-cut, 2-story Historical bird and snag data from 0-5 (Chambers), 10 (Walter), and 18 (Huff) years post-harvest

5 Quantify contemporary use of 25-year old created snags Document nesting species Quantify reproductive success Method: snag- centered observations Study Objective #1

6 Measure avian community response to created snags Stand-level diversity and abundance All bird species Method: Point counts Study Objective #2

7 Assess effect of silvicultural treatments On decay rates and characteristics of snags On snag use by cavity-nesters Methods:  quantify snag status and decay;  assess bird response to snag status Study Objective #3

8 Summary First comprehensive analysis of long ‐ term response of wildlife to created snags Provides information needed to improve effectiveness of snag creation Builds on long-term CoF investment; treatments already implemented, uses existing methods Results will be synthesized with existing data sets for long- term, dynamic perspective.
