I study wildlife in relation to permitting projects under environmental laws.
A great day involves chasing butterflies, looking for birds, finding toads, and getting paid to spend time in beautiful places! Sensitive resources are mapped and studied for breeding, migration, etc. Later comes reporting and relating findings to preservation goals or impact assessments and permitting. Often, there are solution/mitigation goals to be thought through such as designing wildlife undercrossings when a new road is being built or minimizing bird collisions with wind turbines.
Time outside studying nature is the best form of building skills. Pick a passion and follow it. Studying trees or birds or fish or restoration or wetlands or ??? A foundation in ecology and ecosystems functioning is necessary. Other skills that can be gained outside of school are GIS and studying local environmental laws.
Here's the first step for college students
Follow your passion. Take all necessary coursework to obtain a degree in biology or environmental sciences. But know in your heart you are following your passion. You will never be unhappy at work throughout your career.
