Forestry courses, simulations, browser games, and other side projects by Parker Hopkins.

Welcome to CochetopaCo

This is my personal playground for side projects, simulations, and other hobby-driven experiments. Here you’ll find early demos of interactive models, starter code snippets, and curated links to the tools and tutorials I turn to most. Dive in, explore, and feel free to send feedback—or fork the code on GitHub.

Learn the trees behind northern forests

Leaves, needles, bark, a bud, and a cone representing the Northern Hardwoods and Mixedwoods course

Self-paced forestry intensive

Northern Hardwoods & Mixedwoods Dendrology and Silvics

This ten-week course is built for learning trees as a field forester has to know them: from leaves and needles, bark at different ages, twigs and buds, cones and fruit, whole-tree form, site, and the realistic confusers that make identification difficult.

Work through 80 principal taxa, more than a thousand teaching and practice photographs, cumulative scientific names, concise silvics, weekly practicals, and a mastery system that brings weak species back until they stick. Take it seriously over ten weeks or move through it at your own pace.
