This package contains 3D models, textures, materials, and prefabs of 9 different plants, trees, 12 modular terrain pieces, 10 rocks, and a few structures like a house, barrel, and ladder. All non-fruit tree categories contain 10 tree variants, 3 stumps, 3 logs, and 3 branches. All those trees and stumps have a "No Bottom" variation to save on geometry. Fruit trees contain 5 tree variants and its respective fruit. Below are the average poly-counts for some of the models (fruit trees will have more polys):
