You can stake things down if they might be prone to drift down the slope. Surveyor grade stakes are pretty cheap and work well.

Giant zip ties work well to attach cedar trees to a concrete block to keep them from wandering around the pond. You can buy 36" really heavy duty zip ties (used to secure flexible duct work in attics) in bags of 100 for a very reasonable price. Bought in bulk from a plumbing supply store they are not much different in price than a bag of 12" zip ties.
