How many rabbits are there?
We are not sure. In 1993 an estimated 200-300 riparian brush rabbits inhabited Caswell State Park. After severe flooding in the winter of 1997 only one rabbit was trapped during field surveys. While we know population numbers have their ups and downs in their population numbers, we found these poor trapping results alarming. Since 1997 rabbits have been found in the Sacramento-San Joaquin Delta. We believe they survived the flooding by climbing up a railroad embankment. Although this is fantastic news, the threats to the rabbit remain.
