That's a nice looking horse Stig.
First day out on the island to cut the regrowth...yes invasive casuarina.
I'm very pleased, given how bad it was two years ago, the regrowth is pretty minimal. A few stumps sprouted where I didn't get enough Garlon on them, and a few seedlings have popped up in crevices and overhangs.
Still it was HOT and humid, all my clothes soaked to the skin, legs punctured with prickly pear spines, but oh so beautiful. Longtails wheeling around, flying right up within two feet, magic.
Love my SRT for this job, tricky finding some tie in points as they cut down a lot of the bigger trees up on the top, have had to get creative. Most of the stuff I can get with the silky, so not a lot of call to lug the wee 150 up and down.
There are some researchers out there as well, they are studying our endangered endemic skink, they have bottle traps all over the place to catch them, then they are microchipping them, can you believe it! They had all these muslin bags hanging up on the wall in the old magazine in the fort, each with a pissed off skink in it waiting for their turn to be poked and prodded measured and microchipped.
The skinks are endangered from habitat loss and trash, mainly glass bottles. They go in to drink the dregs then can't get out because they have claws not sucker pads. Also there is some evidence of predation by introduced birds like the kiskadee.
I love this kind of work, its very rewarding. After I had cut out all the big stuff two years ago, the longtails came right in to prospect for nests, and the skinks apparently were having a party on all the new bare rock!
Good deal Nic! I'm sure they were getting competent instruction.
keep 'em guessing.
see what I did there. Lol.
