Meeting all students needs.

Physically disabled and visually impaired students have access to all the site's attractions. The Sanctuary's main feature--a path that winds around their two prized ponds and through native cactus and trees--is well paved and marked. A teacher and guide could easily lead any group of students through this path. No exhausting hiking or trailblazing is required. Students in wheelchairs or with other physical disabilities, therefore, would find this trip accommodating. There is also a "Sensory Garden" made specifically for visually impaired students. This garden gives them a tactile experience of the Sanctuary (admittedly, though, it does not offer much for them to touch, and the plants are poorly labeled).
English Language Learners would benefit greatly from this experience because science content is brought to life before them. It might be helpful to have them learn some of the names of the animals before they visit and while there, perhaps recording notes, pictures, questions (in their own language) into a personal science journal. A teacher might also allow students to take pictures using a digital camera. These pictures would provide easy reference for future activities, or could serve as a picture dictionary.
GATE students would find many interesting topics to explore here. They might be given a project to do, such as "Find a way to create a safe-habitat for a creature in your neighborhood." I can see the possibility of many school-sanctuary-home connections happening because of a field trip to the Sanctuary.
