More Than Birds: Note on the IWMM Database

Vegetation Survey Waterbird surveys over the migration and wintering periods have coincided with wetland management efforts for decades. However, bird counts alone cannot be linked to habitat conditions and management actions. Recording habitat conditions and management actions concurrent with bird use represent critical steps in building this link. To this end, participants using [...]

Getting started with IWMM

Establishing Survey Units and Observation Points The first step in getting started with IWMM is to define your survey unit where waterbird counts, unit conditions, annual vegetation assessments and the recording of management actions will be conducted. In the simplest terms, the survey unit is a discrete area with fixed boundaries that stay the same [...]

Framework Versus Manual: Which Do I Use

The IWMM Monitoring Protocol was developed as a rapid assessment of habitat conditions and waterbird use at wetlands during the non-breeding period. During an extensive pilot phase, the protocols were tested via two validation studies and participant feedback was obtained on what was working and what was not. These efforts have led to revised and [...]

IWMM Migration Model Available in Peer-reviewed Journal, Ecological Applications

This manuscript describes a mechanistic model of bird migration based on a bio-energetic approach is designed to be used widely by bird conservation partnerships. The unique aspect of this approach is that it allows us to understand how local actions (e.g., acquisition or restoration) affect flyway or continental populations.  Most non-breeding bird habitat conservation efforts [...]

Revised Protocols Are Here! NEW: Webinar Link!

IWMM’s bird and habitat monitoring protocols were revised in February 2015 based on participant feedback and a habitat metric validation study. IWMM plans to transition all users to the new protocol for the 2015-16 field season. Key revisions and clarifications to the monitoring protocols include: Vegetation composition: this metric has changed from a top 4 [...]

Monitoring and Competing Objectives Between Waterbird Guilds

At many locations managed to provide habitat for waterbirds, managers recognize that maximizing benefits for one group of birds may not necessarily maximize them for another. In fact, without careful planning, efforts undertaken for one group of birds may negatively impact habitat use by another. Part of the reason IWMM focused on waterfowl and shorebirds [...]

Estimating Percent Cover

Examples of Estimating Percent Coverage The IWMM protocol requires estimates of cover to assign water depth classes, estimate habitat class proportions, and assess vegetation composition. We are using a canopy cover approach: defined as the percentage of the survey unit covered by vertical projections from the outermost perimeter of plants’ foliage (Anderson 1986). [...]

Wetland Plant Identification Made Easy

Completing IWMM vegetation surveys requires you identify the most common wetland plants found within a unit. The surveys are completed once annually, typically late in the growing season when dominant plant species have started to senesce. Obtaining an accurate measure of plant community composition (both percent cover and species composition) requires a working knowledge of [...]
