natural communitiesnatural communities

We shall:Explain our vision,Summarize our accomplishments,Describe feedback we have received,Present opportunities we have built,Solicit guidance on future directions.

Multi-institutional collaborative program.

Established in 1988 to document the composition and status of natural vegetation of the Carolinas.

Provides data, data services, soft-ware development and analysis to EEP and monitoring firms.

1.* Document natural conditions with high-quality reference plots.

2.* Derive site-specific restoration targets.3.* Design site-specific restoration plan.4. Implement the plan.5.* Monitor change and trajectory toward

success.6.* Employ adaptive management as

needed.7.* Document the results.

(* = Major CVS role)

Detailed, justifiable, & efficient generation of restoration targets.

State-of-the-art predictions that satisfy the most stringent current and future restoration guidelines.

Tracking of individual trees demonstrates compliance with US-ACE requirements.

Greater plant success through selection based on past species performance and site characteristics.

Early detection of likely failure so that corrective action can be taken.

Robust and documented planning that should be resistant to future litigation by diverse interest groups.

Optimized data collection procedures.Consistency between years & monitoring firms.Automated analysis, QA/QC, report generation,

& evaluation of plans.Improved ease & efficacy of plant selection.Early detection of project problems or success.A methodology that is scalable

to more robust and challenging regulation.

Optimized for field efficiency and repeatability.

Resources include manuals, datasheets and a data entry and reporting tool.

Scalable to meet future requirements.

Complies with US-FGDC National Vegetation Classification Standard.

Then print datasheets…

Baseline data preprinted

Quickly find stems with the printed map.

Efficient format, pre-populated fields, flagged errors, picklists of valid options,

etc.

You asked -- What is gained from measurements collected using the CVS-EEP Protocol?Variables measured are mandated by EEP, not CVS.EEP initially required multiple types of measurements because it was unclear which ones would be most useful in assessing stem success. Available data from EEP MonitoringFirms will now allow CVS to assess the utility of each field measurement (e.g., ddh, height, DBH).

Phase 1 – Web tool for documenting reference conditions by NVC types (partially implemented).

Phase 2 – Constrain NVC types and plots by geographic region (in development).

Phase 3 – Web tool for predicting a target from site conditions (prototype complete -- future development).

Data flow for identifying target community and planting list

Internal decision tree showing how site data predict community

Vegetation types classified

Critical environmental fields defined

Restoration sites chosen and environmental data

collectedRestoration sites matched

to vegetation type

Planting list generated from vegetation type

species list

Prototype tool predicts target vegetation type based on site data.

Planting lists could be automatically generated from community data.

Alternative to searching out reference areas – just look them up in minutes in your office.

Greater likelihood of selecting species that will grow well at your site.

More effective restoration – which is better for our state and better for you.

Better assessment & prediction of change, success, and failure over time.

Automatic generation of reports for US-ACE.

out?What am I getting into?

CVS will develop a tool that draws on multiple datasets to aid in selection and evaluation of species for planting designs. This will help: Design firms in selecting planting

materials, EEP in evaluating proposed

planting materials, Growers to better predict demand.

Dataset 1: Community composition, as documented in the Vegetation of the Carolinas database,

Dataset 2: Geographic distribution, as documented in the SE Floristic Atlas,

Database 3: Species environmental tolerance,as documented in the CVS reference plot database.

Examine the success of material (species, source, size) used in earlier EEP projects on similar sites.

Past success can be deduced from CVS-managed data from monitoring studies.

How many monitoring plots are needed?Which plant attributes should continue

to be measured in the field?How often should plots be monitored?Should there be a

mixed monitoring strategy for tracking stems and observing site-wide variation?

Larger ddh and taller height both resulted in higher survival of stems.

We built a model to predict survival based on ddh and height. The model did little better than a model based on height or ddh alone.

DBH does not predict stem survival until stems reach 5 cm.

≥ 250 cm maybe?? cm precision

Data being processed by CVS could be used in various ways to make restoration and monitoring more efficient and effective.

We could facilitate and enhance this process with regular meetings of CVS with EEP, US-ACE and ACEC firms.

CVS could reserve a portion of analysis time for responding to issues raised at those meetings.

Potential return on investment: Cost savings > $200K/yr … if continued.

CVS is now prepared to develop state-of-the-art tools that address key components of the CVS-EEP vision.

Tools currently available and those under development would take advantage of the results of our past CVS-EEP collaboration and allow EEP and its monitoring firms to do a significantly better job more quickly with less risk and at substantially less cost.

.

If EEP does not pursue these opportunities at this time, key CVS staff will not be retained and the described opportunities will likely vanish.

Loss of the CVS-EEP partnership would result in loss of data management & report generation. Moreover, it would significantly increase costs for both EEP and ACEC firms.

Continuation of the CVS-EEP collaboration would ensure ongoing maintenance of the EEP-CVS databases for monitoring and reference data and tools for their effective use.
