Practice 7: Census Counts

Census counts — the systematic monitoring of wildlife populations on your property — serve as the scientific backbone of your wildlife management program. While the other six practices focus on improving habitat and managing threats, census counts measure whether those efforts are working. Consistent population monitoring data over multiple years is one of the most powerful components of a wildlife management annual report.

What Qualifies as Census Counts?

Census counts encompass any standardized method of monitoring wildlife populations, species composition, or population trends on your property. The emphasis is on 'standardized' — conducting surveys the same way, at the same time of year, along the same routes, so that results can be compared year to year to identify population trends.

You don't need a biology degree to conduct effective census counts. Trail cameras, simple driving surveys, and systematic observation can all produce useful data when conducted consistently.

Census Counts Activities for Your Annual Report

Spotlight deer surveys

Driving a fixed route after dark with a spotlight, counting and classifying deer by sex and age class. Conduct at the same time each year (typically August-October) for comparable data. Record bucks, does, fawns, and unidentified deer.

Trail camera monitoring

Deploying trail cameras at fixed stations year-round to document species presence, relative abundance, and activity patterns. Establish a minimum of 1 camera per 200 acres for meaningful data density.

Bird point counts

Standing at fixed locations for a set time period (usually 10 minutes) and recording every bird species seen or heard. Conduct during the breeding season (April-June) when birds are most vocal and active.

Breeding bird surveys

Systematic surveys targeting specific bird species during nesting season. Particularly valuable for quail — listen for male bobwhite whistles along a fixed route during May and June mornings.

Harvest data collection

Recording detailed information on every animal harvested — species, sex, age (estimated or from jaw aging), weight, antler measurements, body condition. Harvest data is the most underutilized census method.

Track and sign surveys

Walking fixed transects and recording wildlife sign — tracks, scat, rubs, scrapes, nests, burrows, and feeding evidence. Particularly useful for species that are difficult to observe directly.

How to Document Census Counts

Census count documentation should include the survey method, date, time, weather conditions, route or location, and complete results. For spotlight surveys, record the route on a map and use the same route each year. For trail cameras, log deployment dates, camera locations, card retrieval dates, and a summary of species and quantities documented. Export sample images showing key species. For harvest records, photograph each animal with a measuring tape for reference.

Ecoregion Considerations

TPWD recommends specific survey methods for each ecoregion based on the wildlife species present and terrain characteristics. Spotlight surveys work best in open terrain (Edwards Plateau, Rolling Plains, South Texas Plains). In heavily forested areas (Pineywoods, Post Oak Savannah), trail cameras and bird surveys are more effective. Breeding bird surveys are valuable in every ecoregion and provide the most species-diverse data set.
