While it is not always possible to see the wildlife that enter agricultural fields, it is possible to identify these animals through the signs that they leave behind. The Track and Scat Glovebox Guide is a small, compact user guide that contains information about 31 wild and domestic animal species that have been recognized as possible trespassers in fresh produce fields in Southwest Arizona. A photo of each animal is provided, along with a representative image of the animal’s tracks and scat. Track and scat descriptions are also provided to assist with field identification. Each photo includes a one inch horizontal bar to provide a reference for size of the tracks and scat for each entry.
The guide was developed as the result of an animal intrusion study conducted by University of Arizona scientists. In the study, animal scats were collected and analyzed to determine pathogen load in each animal’s feces. Scat samples were also analyzed for the potential risk associated with pathogen transfer from feces to crops. Results from this study have been compiled to create a risk index. The risk level associated with each animal’s scat is included on the animal information pages within this guidebook.
Before you begin
The appearance of tracks and scat may vary depending on environmental settings, soil conditions, animal nutrition and actual size of the animal. All track and scat representations outlined in this guidebook are intended to be used as broad references to assist with the identification of a trespassing animal.
Feces identification can be dangerous. Be safe and avoid handling droppings without proper protection. Also, be cautious when in close proximity to scat; you do not want to inhale any bacteria as some diseases may be spread through airborne particles. Observe feces carefully, without touching it unless it is to remove the feces from the field. When you do touch it, use a tool and/or properly gloved hands.
Remember, all feces should be treated as high risk. Exercise caution when handling fecal material.
How to use the guide
Whether you spot an animal track or a small intestinal gift in your field, you will be able to identify which desert southwest animal left its mark by using one of the diagrams on pages 20 and 21. Search by Track Type or Scat Shape to determine the risk associated with your field invader’s feces, and to determine the level of potential risk that may affect the safety of your fresh produce. If you would rather search by Animal Name, the index on page 52 lists each animal in alphabetical order and differentiates domestic versus wild animals.
To assist with measuring tracks or scat during field observations, use the ruler provided on the back cover. Remember to be careful when taking measurements and avoid touching scat unless you are wearing gloves and/or have a tool to assist you.
