John Montgomery is a biologist and GIS specialist with 10 years of experience. He has served as a project lead for various biological monitoring projects throughout the Sacramento-San Joaquin Delta and Northern California. John specializes in monitoring freshwater life stages of juvenile and adult salmonids using a variety of methods, including telemetry (using ATS, VEMCO, and HTI technology), electrofishing, rotary screw traps, snorkel surveys, seining, redd surveys, angling surveys, resistance board weirs, and fish identification using image processing and pattern recognition.
John’s expertise in fish handling is complemented by a variety of environmental sampling experiences, including measuring river discharge, deploying water pressure loggers, benthic and plankton sampling for invertebrates, large woody debris inventory, water quality testing, habitat typing, and substrate quality analysis (particle size composition, distribution, and permeability). He conducts geo-spatial data collection using Trimble GPS and land survey equipment, and performs GIS data management and representation using ArcGIS.
