Under the Lacey Act of 1990  (d) creating wildlife management areas for the traded species is mandatory

Explanation:

The Lacey Act of 1900,refers to a conservation law in the United States which prohibits illegal  trade of  wildlife, fish, and plants.

The Lacey Act Declaration, also known as PPQ Form 505,is a form that certain importers of wood products are required to submit to the United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS)

The Lacey Act of 1900 in  United States bans the illegal trafficking of the wildlife.  In 2008, this Act was amended in order to  include plants and plant related products like  timber and paper.

This Act was  the world's first ban on the  illegally trade of  wood products.

Thus under the Lacey Act of 1990  (d) creating wildlife management areas for the traded species is mandatory

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
