Caveats to Preservation and Enhancement- Can be difficult/expensive to implement on a large scale.- Some “beneficial” plantings can increase pest arthropods.- Not proven to work in all systems.- Eliminating/reducing use of broad-spectrum insecticides may result in production loss.- Must take valuable land out of production for attractive plants.
