Not exactly conservation, but there's plenty of computational work (and funding!) in plant biology.

I do web development and data engineering for plant phenomics automation in a plant bio lab. Crop optimization (e.g., for abiotic stress resistance, reduced fertilizer requirements, atmospheric carbon sequestration, yield) basically requires digital surveillance infrastructure on the same scale we've (regrettably) developed for humans, except for plants. Nobody really understands how phenotypes develop as a function of genetic, physiological, and environmental factors; but we need to if we want to maintain the viability of agriculture in the face of climate change etc.

You won't get paid like you would in a more traditional software development position, but it's enough to live on. Let me know if you'd like more information.
