Detecting Temporal Trends in Freshwater Fisheries Surveys: Statistical Power and the Important Linkages between Management Questions and Monitoring Objectives by Jean Brennan, last updated: Feb 20, 2015 01:15 PM
by T.Wagner et al., ABSTRACT: Monitoring to detect temporal trends in biological and habitat indices is a critical component of fisheries management. Thus, it is important that management objectives are linked to monitoring objectives. This linkage requires a definition of what constitutes a management-relevant “temporal trend.” It is also important to develop expectations for the amount of time required to detect a trend (i.e., statistical power) and for choosing an appropriate statistical model for analysis. We provide an overview of temporal trends commonly encountered in fisheries management, review published studies that evaluated statistical power of long-term trend detection, and illustrate dynamic linear models in a Bayesian context, as an additional analytical approach focused on shorter term change. We show that monitoring programs generally have low statistical power for detecting linear temporal trends and argue that often management should be focused on different definitions of trends, some of which can be better addressed by alternative analytical approaches.
Spatial and Temporal Dynamics in Brook Trout Density: Implications for Population Monitoring by Jean Brennan, last updated: Feb 20, 2015 01:15 PM
T.Wagner et al., Abstract Many potential stressors to aquatic environments operate over large spatial scales, prompting the need to assess and monitor both site-specific and regional dynamics of fish populations. We used hierarchical Bayesian models to evaluate the spatial and temporal variability in density and capture probability of age-1 and older Brook Trout Salvelinus fontinalis from three-pass removal data collected at 291 sites over a 37-year time period (1975–2011) in Pennsylvania streams. There was high between-year variability in density, with annual posterior means ranging from 2.1 to 10.2 fish/100 m2 ; however, there was no significant long-term linear trend. Brook Trout density was positively correlated with elevation and negatively correlated with percent developed land use in the network catchment. Probability of capture did not vary substantially across sites or years but was negatively correlated with mean stream width. Because of the low spatiotemporal variation in capture probability and a strong correlation between first-pass CPUE (catch/min) and three-pass removal density estimates, the use of an abundance index based on first-pass CPUE could represent a cost-effective alternative to conducting multiple-pass removal sampling for some Brook Trout monitoring and assessment objectives. Single-pass indices may be particularly relevant for monitoring objectives that do not require precise site-specific estimates, such as regional monitoring programs that are designed to detect long-term linear trends in density.

NALCC Project Metadata spreadsheet w/ coding by Jean Brennan, last updated: Feb 20, 2015 12:27 PM
Scott's email: As a starting point for discussion, Maritza and I have cross-walked our project pages with the fields in the National Project Catalog. We've color-coded them based on the degree to which they match (e.g., green = exact match, red = something in National system that we don't have). For the AppLCC, we also included Rose's cross-walk of your fields with the National Catalog.

XWalk - (Key File) - Crosswalk on SHC & OTHER frameworks incl. AppLCC by Jean Brennan, last updated: Feb 20, 2015 11:00 AM
This is a KEY file as it (1) presents a "crosswalk" between all the various (regionally-referenced) conservation frameworks (cycle graphics of various names): (a) SHC (Strategic Habitat Conservation) Elements, (b) [NE-FWS; Ken Elow] Northeast Regional Conservation Framework (NRCF) = "NALCC model" = "Albany Workshop" cycles/elements, (c) SWAP (state wildlife action plan) Elements, (d) [SE-FWS; Bill Uihlein] Southeastern Conservation Adaptation Strategy = "SECAS", .......AND this shows (e) the alignment of the AppLCC's 5-Year Work Plan (i.e., the Goal, Objective, and Task) shown as a three-digit code.

Task 4 Responses V3 by Web Editor, last updated: Feb 20, 2015 10:58 AM
Elements of success include both tangible (products, funding, actions with direct links etc…) and intangible components (the synergy of the partnership to foster ideas and relationships which may lead to changes in actions by participating collaborators etc…). Our response to this request for information on performance measures, and about project funding patterns, places the emphasis of success more on the measures that are tangible and directly tied to LCC action, but does not appropriately capture the value of a broad partnership. This should be a topic of conversation with the NAS panel.
