I have seen spectacular
cactus habitats in many countries, but, surprisingly, my favorite
cactus habitat is at the New Mexico-Texas border, just north of El Paso
and Ciudad Juarez, on the four-lane high-speed NM Highway 404, four
miles east of I-10 and the town of Anthony. These are public lands in
the Franklin Mountains: the Sierra Vista Trail on BLM lands in New
Mexico and Franklin Mountains State Park in Texas. Along an old jeep
track perpendicular to Highway 404, there are at least 21 species of
cacti (see checklist, below). This is the only known locale in New
Mexico for Coryphantha dasyacantha. Clumps of Coryphantha sneedii exist
along the trail with over 100 stems. Some specimens of Glandulicactus
uncinatus have 8-9 inch long spines. The largest specimens of
Echinomastus intertextus I have ever seen are less than a hundred feet
from the highway, with a dozen flowers open at once. There are a
profusion of forms of the hybrid Echinocereus x roetteri, along with
its two putative parents. I will show photos of 20 cactus species here,
many in flower, plus the one natural hybrid. I will show another 5-7
taxa that are probably also here, all of which I have seen nearby,
which I now need to make a concerted effort to find when I next visit
Anthony Gap.
I am a professor of biology
(cross-appointed in both mathematics and interdisciplinary studies) at
Carleton University in Ottawa, the capital of Canada, but seem to spend
most of my days living at the end of a lake in Kawartha Highlands
Provincial Park. While this is boat-access (or snowmobile-access) only,
8.5 km from the nearest road, electricity is supplied by cables at the
bottom of the lake, so is hardly rustic. My cactus gardens overlook the
lake, so close that snapping turtles often lay eggs, digging up my
cacti in the process. My cacti are now under several feet of snow. In
addition to research on cacti, I study evolution of sex, philosophy of
science, mathematics for quantifying diversity, and academic freedom.
In the mid 1990s, I lived in Las Cruces, NM, but ironically never
stumbled upon Anthony Gap until 15 years ago, as I was moving to Canada.
