ABSTRACT THE RELATIVE INFLUENCE OF MICROHABITAT CONSTRAINTS AND ROCK CLIMBING DISTURBANCE TO CLIFF FACE VEGETATION COMMUNITIES Kathryn Lynne Kuntz University of Guelph, 2004 Advisor: Dr. Douglas Larson This study is the first to determine the relative influence of pre-existing microhabitat constraints vs. direct rock climbing disturbance to the cliff face vegetation communities of the Niagara Escarpment in southern Ontario. Climbed and unclimbed cliff faces were sampled quantitatively for vascular plant, bryophyte and lichen species richness, percent frequency and community composition, microtopographic feature size and frequency, and measures influencing microclimate. Results revealed that certain microhabitat conditions are related to increases in the richness and cover of cliff face vegetation, and that rock climbers select for different microhabitat conditions when establishing climbing routes. No decreases in vascular plant, bryophyte or lichen species richness or cover on climbed cliff faces were attributable to direct climbing disturbance (I added these italics-DB). Pre-existing microhabitat conditions explained greater proportions of variation in vegetation community composition across unclimbed and climbed cliff faces than climbing disturbance. A policy is presented that permits new climbing route establishment with limited impact.

Fawk yeah some one else that spent all last weekend driving around instead of climbing something!!!

yeah but I will be spending my birthday in a tent with an 83 year old man instead of in a pub with cute girls

Chek at Cheakamus Canyon.

happy birthday y'old lady

There is no such thing as the "Inland Northwest". There is only the "Near East" (Leavenworth, Skaha etc) and the "Far East" (Rockies) and then "Siberia" (anything east of the Rockies, eg. Calgary, Chicago, Florida)

Yeah, you just did, pervert!

or was that car bomb and mortar round the feuding tradsters and sprotclimbers taking it to another level in the bolt wars amidst the granite domes of Renton.

Damn why are you still in Iraq ??? Is the dune skiing really that good?

I bet Selma Hayek could kick her ass

not to mention just bad photos of bad places to be

or even stuff like this?

weird colors from bad exposure

out of focus

what about broke down unimogs

so what you are saying is that Islam is conservative, not liberal? the horror! I expect you to become liberal immediately.
