Is this not simply the trade-off that every design feature needs to balance? Native grasses might be there for environmental, aesthetic, strategic, or ease of maintenance reasons. If the price is that a few people die a painful premature death, then I don't think that is unreasonable - as long as it isn't me.
My course is alive with deadly snakes in summer - leave the buggers alone and they will repay the courtesy. If you must head in after a ball, take a five iron and make lots of noise. I don't think we have ever had a snake bite in 90 years.
On the other hand we have had lots of falls and accidents from people toppling into bunkers etc, resulting from slopes, contours and too much red wine at lunch, plus a few heart attacks from old duffers slogging up the hills. Are we to flatten the course out to prevent those?
