<div class="PlainText">Goats are definitely off, I found they ate everything except what you
<br>
wanted them to. Very cute though. The low profile "Robo mower" idea <br>
has merit.<br>
<br>
The best I've seen was a wild flower seed mix, that all grew only a <br>
couple of feet high max. They probably needed some weed wacking a few <br>
times a year, but much less than grass. Totally depends on the <br>
location. On the wet side of Maui, you would have the array disappear <br>
into the jungle in 6 months, never to be seen again. In the desert, it <br>
might be sage brush after 10 years.<br>
<br>
I worked on a project once that used 4" deep gravel spread over 160 <br>
acres. Total disaster in my opinion; think how many cubic yards had to <br>
be trucked in. Vehicles got stuck in the loose gravel, it slowed <br>
everyone down, and 3 ft high weeds were growing up out of it in 6 <br>
weeks. Then when you went to weed wack, you had gravel projectiles sent <br>
flying into the glass.<br>

>> For anyone involved with large-scale ground mount systems, I am curious about the various methods being used to control vegetation. My sense has been that O&M service providers generally gravitate toward gas mowers/trimmers with spot application of chemical
herbicides. Does anyone have any experience with alternative methods, such as specialized seeding (e.g. pollinator-friendly), groundcover plants, goat herds, maybe even robotic GPS-guided mowers? I'm especially interested to hear from anyone who has analyzed
the pros/cons of different methods or who can speak to any approaches that might be site-specific.<br>
