2. This presentation was given at the 2002 State FIA Coordinators Meeting held in St. Augustine, FL October 9 and 10, 2002. This presentation is intended to introduce the State Coordinators to the P3 Vegetation Diversity and Structure indicator program. Results presented here are PRELIMINARY and only based on subsets of data gathered in the SC pilot study. For updated information, please contact Sharon King at 865-862-2044 or sharonking@fs.fed.ussharonking@fs.fed.us This work is funded by USFS Cooperative Agreement number SRS-02-CR-11330145-055. Measuring Vegetation Diversity and Structure in the Southern Region

3. What Is the P3 Vegetation Diversity and Structure Indicator? The measurement of species composition and vegetation structure of vascular plants on Phase 3 subplots Includes all trees, shrubs, herbs, grasses, ferns, and fern allies (horsetails and club mosses)

4. Objectives of the Program To assess forest health in terms of structure, diversity, abundance and rates of change of vascular plant species Particular interest in the following contexts: native vs. non-native species wildlife values wildland and prescribed fires

5. South Carolina P3 Vegetation Indicator Pilot Study Objective: To evaluate the effort and costs associated with collecting all vegetation indicator variables on P3 plots for the state of SC South Carolina had 32 P3 plots evaluated Methods were those described in the March 2002 National Field Manual

6. Questions We Hoped to Answer From the SC Pilot Study What kind of effort (botanist hours) is required to collect the data in the field using the outlined methods? What is the best configuration for data sheets? How much information is gained by each successive quadrat and subplot?

7. More Questions... Are the variable measures sound and repeatable? What kind of effort is required to document and identify unknown species? What kind of effort is required to manage the data? How does the Southern Region fit into the national program?

8. Pilot Study Timeline April: Training in Macon, GA with Beth Schulz, National Indicator Advisor May/June: Started the field season with 3 trips to SC; collected data from 4 plots –First plot done together –Other plots blind checked June 18: Botanist started solo work with State P3 crew September 17: Field work completed October 1: Data turned into SC on 21 plots, 11 still being processed

9. Vegetation Indicator Field Methods Every plot contains four P3 subplots Subplot = 24 ft radius circle Every subplot contains three 1-m 2 quadrats at 30 o, 150 o and 270 o

10. Quadrat Measures (1m 2 frame) Cover of ground variables in quadrats to 1% Cover of all species in, or overhanging quadrat (up to 6 ft) to 1% 6 ft.

11. This quadrat contained 9 species

12. Subplot Measures (24 ft. radius circle) Identify all additional species on subplot and estimate cover to 1% This subplot contained 33 additional species, 46 total Plot Center

13. More Subplot Measures For every species, layer of greatest foliage cover is recorded For all four layer classes, total cover (of all species combined) is estimated to 1% Layer Classes 0-2 ft. 2-6 ft. 6-16 ft. 16+ ft. Vaccineum tenellum : Quadrat 3: 37% Subplot: 10% Layer: 1 (0-2 ft.) Total Cover (all spp.) in layer 1 (0-2 ft): 64% Example

14. 0-2 ft. 2-6 ft. 6-16 ft. 16+ ft.

15. Dealing With Unknown Species Species not known in the field are collected, tagged and bagged All unknowns are assigned a number Specimens are keyed, or logged and pressed Protocol states that pressed unknowns are sent in to a herbarium for identification

16. Preliminary Study Results (Logistical) Collected data on 32 Plots across state Completed 72 out of 128 subplots (56%) 115 hours spent on plot (Based on a subset of the data, does not include travel, locating plots, set-up, or any follow-up work off plot)

17. Preliminary Study Results (Biological) (From analysis of 10 plots, 26 subplots) Total number of “species”: 353 Ave. species per quadrat: 7 [3-15] Ave. species per subplot: 38 [14-78] Average unknowns/subplot: 9 [0-35] Completed plots: 1 unknown/subplot Estimate 75-130 unknowns for season once processed

18. Time in the Field (per subplot) (From analysis of 9 plots, 21 subplots) Quadrats: 24 min. SP Search, T&B: 33 min. Cover & Layer: 21 min. Overall Layers: 4 min. Miscellaneous: 14 min. Time to complete subplot ~ 1:36 ** Numbers do not reflect time to find or mark off plot Note: Analysis not complete!

19. Actual Time Spent on All Tasks (Projected from analysis of a subset of data) Field time = 115 hrs Plot set up = 32 hrs Travel = 114 hrs Specimens/data sheet clean-up = 115 hrs Entry into NaTally = 22 hrs Time to complete pilot ~ 398 hours Note: Analysis not complete!

20. Summary ~ 398 hours to complete 56% of subplots in state Estimate ~ 616 hrs to complete all subplots (15.5 wks @ 40hrs/wk) Practically equal amounts of time needed for travel, data collection, and data management To implement region-wide we will need qualified botanists with specialized skills May need to be creative with funding and logistics on a state by state basis

21. What’s Next From Here? Compile complete data set from pilot and determine resource needs for region-wide implementation Communicate with other regions to compare our experiences and share information Evaluate goals, study methods, personnel and funding resources/needs to plan for implementation of the Vegetation Diversity and Structure Indicator program for all states in our region
