These landowners are evaluating the outcome of grazing on lands infested with leafy spurge. Which side of the fence was grazed by cattle? Which side by sheep?

Cattle is on the right, and sheep is on the left.

When you posted the question, you just clicked on an image from google images and inserted that link (which the forum doesn't read as an image file). Gavinnupp appears to have just inserted another image of the same species in his post answering the question.

Alright,

Image
1. Identify the two species pictured by their Scientific and Common names.
A plant
B animal
2. Explain these two species' ecological relationship.
3. Scenario: You work for the Scioly Parks and Wildlife Department. It has come to your awareness that Lake Scioly has become clogged with species A, which is decreasing boater and angler satisfaction in Lake Scioly State Park. Formulate 2 potential plans of action to control species A, using mechanical, biological, chemical, or other means. Evaluate how long-term effective and ecologically sound these plans are.

im guessing
1A) Giant Salvinia / Salvinia molesta 1B) Salvinia Weevil / Cyrtobagous salviniae 2) Species B is a predator/biological control of species A 3) Method 1: Use the Salvinia weevil as a biological control. This weevil has been generally successful in controlling the Salvinia as a longterm solution, and ecologically is safe for a biological control, as it has not become invasive itself. Method 2: Use machines to remove the Salvinia through mechanical control. This is generally only effective for smaller scale infestations and is not always 100% effective, but it is widely regarded as rather ecologically sound as other species are disturbed minimally.
