The proof is in the increase in animals. Just because a planting grows it dosen't mean it's good for the deer/wildlife. After planting put an exclusion basket in the planted area. Measure the difference in growth from the inside of the basket to the outside of the basket. This will give an indication of animal usage. Next, and this is the good part, keep a record for the next 3-7 years and you should know if the product you are using is the catalyst for animal increase.
