The best horse and rider combination we've seen in Yosemite was a couple of years ago, when we were hiking down the steep trail from Mono Meadows to Illilouette Creek and beyond. Struggling up the other direction was a party of three people and a horse. The two men were carrying backpacks, and one of them was leading horse who also had a pack...but the woman was actually hanging on to the horse's tail with both hands and letting the horse pull her up the hill!

We started laughing, but they explained that the woman was actually not capable of walking all that way, and had been riding the horse, until it came up lame. This was the solution to getting all of them back out again.

I still chuckle about it...and admire that patient horse!

I have no problem with sharing the mountains with horse packers. I don't particularly care for the cr@p (because of the flies) but it's biodegradeable and it's sometimes a bit disconcerting to get water out of a stream only to find that several switchbacks further up, a horse has cr@pped in the same stream but I'm OK with that also I've hired a packer a number of times to carry my hugely heavy backpack (in my younger, less wise "heavy" days) up the Copper Creek trail in Kings Canyon along with yours truly. It sure makes things a lot easier for those that can afford it and someday I may be forced to ride when I can no longer walk.

Once I was fortunate that a pack train was going over Granite Pass and I could just tag along so that they wouldn't have to lead my horses back - note: packers normally take you as far as you can ride in 1/2 day since they also have to return the same day . I was able to make it over the Pass in one day and camp at Shorty's Meadow with the packer (and his whisky bottle...). Made pretty good time on that trip but my rear was sure sore for awhile from the horses jumping down from granite step to granite step... Just for the record, I am not a horse lover nor am I a rider. In fact, the only times that I have ever ridden have been with horse packers dropping me off somewhere for the start of a long hike in the Sierra and it's always been an adventure.

I believe that horse packing is one of the few things still available to horses that allow them to be something more than just a pet and gives one somewhat of an idea as to what the horse meant to a world before mechanization. They are relics from the "Before Time" that I honestly don't mind seeing put to good use :-) Cows and sheep are a different story...

Yes, you make a very valid point about giving horses jobs. My girls absolutely love to be at work. They like to be rewarded too of course with treats etc, but the happiest horses I know are horses that have a job and work regularly! Mine get ridden every day just for the record, and always greet me at the gate vying with each other for attention and calling to me "pick me, pick me!"

We all have some level of impact when going into the backcountry but the main problem with horseys is that their impact is disproportionate to the number of people they bring in. On average, a single visitor uses 2 or 3 stock animals on a trip. The impact depends on a number of factors but the main ones are the skill and interest in minimum impact of the wrangler; whether they graze; and what elevation they're used in.

Major impacts are:

1) Giardia and other pathogens in manure. A study in Yosemite has found that about 6% of horses and mules carry giardia and about 3% carry camplobactor. That may not seem like a huge number of actual animal carriers, but that's literally thousands of cysts shed per pile of manure. Then you can figure out how much of that has a high potential of getting into a water source (say within 200 feet of a stream or lake when it rains). This same study also measured the amount of manure deposited per mile per animal as well as estimated the number of cysts per pile of manure (let's hear it for graduate students!)

2) Horse piss carries a huge load of nitrates. Horses and mules almost unfailingly piss into a stream when they stop to drink and, if memory serves, can be as much as 20 gallons per piss per animal. Probably no pathogens involved here, but it's a major source of nitrates for algal blooms in streams and lakes. (I'll also add a neat bit of trivia: in an 1895 Sierra Club Bulletin, campers were advised to take lemons with them on Sierra trips to hide the taste of sheep piss due to the thousands of sheep in alpine areas).

Lakes and streams near camps that are used by stock have higher levels of e-coli than lakes and streams used by only backpackers which are higher than those used by no one.

3) By actual measurement, campsites that are regularly used by stock users are larger in area of denuded vegetation as well as having more mechanical impacts in the site itself (ax marks on trees; areas pawed out where stock have been tied; manure not raked out of camp; flies & etc.). Camps used mostly by hikers don't have as large an impact zone and far fewer of those other impacts.

4) When horses are allowed to graze on local vegetation, the impacts can be huge, depending on regulations & enforcement and the skill and interest of the packer. Many meadows look like pastures by late August. The grasses are cropped down low, there are no flowers or even dried flowers of either grasses or herbs. This is a direct impact on the aesthetics of a wilderness area. All visitors should be able to look at a meadow in any stage of its natural order -- from first shoots of green grass, to flowering, to dried flowers waist high:

...a place of knee high grasses, ripe and open panicles drifting on the moving air, luminous-bronze in the backlight. It was a very different emotional experience of a mountain meadow, and entirely consistent with what one might rightly expect of national park backcountry.
-- Randy Morgenson

Horses will also "roll" after being released to graze. This is where they just drop down on the meadow and roll around like a dog. This can create a huge pit devoid of vegetation in a fragile alpine meadow. Once established, it will take decades to recover.

Where regulation is poor or not enforced, there are long-term ecological changes such as reduction of species diversity as well as other changes in diversity.

5) Horses are also responsible for introducing non-native vegetation. This is becoming an increasing problem in many areas as these grasses crowd out native grasses and seriously disturbing a meadow's ecology.


To a certain extent, it's less a question of should horses be allowed, but how to calculate everyone's ecological impact (aka footprint) on an area and what an acceptable impact (carrying capacity) is per person -- not per animal as it's currently calculated. The wilderness area is not there for the animals to visit, but for the people, however they might get there. I would come up with some number for impact of a person on foot and the impact of a person on a stock-supported trip. I think it would be possible to derive a carrying capacity for different eco-zones/elevations from that number.

The interest for determining such a constant in government agencies is close to zero.

Good stuff, George. I'm thinking that since Yose stocks all their HSC's via mule train, it's a foregone conclusion that horses/mules are here to stay. um, my guys don't piss 20 gallons at a time.. maybe 1 gallon max/per pee.

I followed a pack string to Vogelsang once. not fun, but it is their supply line and that's why the trail is built the way it is. Obviously, off the beaten path, those with horses can be more aware (not implying they aren't)

um, my guys don't piss 20 gallons at a time.. maybe 1 gallon max/per pee.

Ooops. You're quite right. Don't know how that number got into my head. Maybe it was per day, but that's not even right. I looked at per day, and some estimates give 10 to 15 gallons. Still, that's a lot of nitrates, which was the only point. Also, watching horses at crossings, I'd say it's more than a gallon, but WAY below 20... .

thanks for the save!
