Just be aware that habitat conservation/restoration is rarely as simple as spreading some seeds. Sometimes removing some invasive plants that are out competing the natives is enough, other times is as complex as reintroducing predators. I would recommend finding a volunteer program to work with so you can ensure you're helping where it's needed most.

If you're in the united states, I recommend checking out your state's Master Naturalist program. In my state, it involved a short classroom training course with several "field trips" to help with the training process. The group helps coordinate volunteer opportunities in the community. The program is an offshoot of the Master Gardener program which I think focuses more on maintaining residential landscapes.

No matter what you decide to do, it's great to want to help.

I think our actual library is just in process of starting one.
