I think it'd be useful for us to have another two abilities at lower levels, much like Arbor Call and Lay of the Land, but differentiating the two types of harvesting spots from one another.

For example, Arbor Call will show us logging spots, while Arbor Call II will show us harvesting spots. Current Arbor Call II will change to Arbor Call III, showing us the highest level logging spot, and a new Arbor Call IV will show us the highest level harvesting spot.
