In March of 1988, we visited Isla Guadalupe, Baja California, for three days. On the 28th, we camped under the Guadalupe Cypress (Cupressus guadalupensis) grove in the central highlands of the island and another group camped at the spring in the upper portion of the large crater in the northern part of the island. On the 29th, we visited the pines and palms in the northwestern part of the island. On the 30th, the group landed at the south end of the island. Visitation to the island is restricted by the Mexican government and allowed only with proper permits. A new graded but steep and rugged road extends from the northeast anchorage past the cypress grove and the newly surfaced airstrip to the village near Melpomene Cove at the southern end of the island. Feral goats, cats, and dogs are common. The goats and cats have decimated the biota of the island (Lindsay 1966; Howell and Cade 1954), especially in the northern parts.
