With backpacking, Leave No Trace has some rather straightforward rules.

1. don't leave the hard surface trail. There's sensitive environment off of it that you don't want to step in. follow durable surfaces to a cathole spot
2. Limit your impact by having a compact campground.
3. leave what you find

The problem is you should be ignoring LNT and transcend it. LNT is a great concept for car camping and day hiking. It falls apart when you get away from formal campground with flush toilets and trash cans.

Do NOT walk 200 feet in a random direction to camp, use the restroom, collect water. https://lnt.org/how-far-is-200-feet/

Getting off trail means changing the trail profile, it's creating a demand path. it means digging a cathole randomly in the woods, no concern for if the place you pick is a sensitive ecological are.

You should be picking established areas only. Do not add to the problem. It's far better to not go 200 feet than to walk into undistutrbed or recovering nature. You should camp next to the trail rather than disturb the woods further.

We Can't All Use the Restroom in the Same Spot

On popular trails people have to spread out more and more to not find a spot already dug up. We can't all travel on a durable surface to the perfect untouched ground. Formal toilets are ever more important than before. Better to deal with a pit toilet than the impact of catholes.

Dispersed Camping Doesn't Mean to Make a New Campsite

The Forest Service often allows dispersed camping anywhere along a trail in so many of their Wilderness Areas. I was on one FS trail and could find a campsite over and over and over. One area had a dozen in a quarter mile, each with a fire ring. That's a new campsite every 30 seconds or so.

Find an established campsite.

Change Things. That's right, LNT says you can change things. But it does it in the wrong way.

It says to remove fire rings and manmade items, but all that does is enable someone to find your scattered rocks and make a ring in a new spot.

Instead better define the campsite. Clean it up, line it with rocks. Stop change by stopping new change.

Removing Plants

We need to spend billions of hours removing invasive plants across the country. If we don't we'll end up with fields of invasive plants.

Controlled Change is Important for Wildlife

As is doesn't protect bears. Think about a camping area with a group of 4 people You find the perfect camping site on a bluff with a view. The first night it's used, everyone camps in the middle, cooks in the north and bear hangs in the south For the next group camping is to the south, cooking in the middle and for hang to the north. Bears now know it's all a place for food. All for lack of definition of purpose.

Controlled Change Needs to Become the Standard

LNT needs to think about redoing its standard around the concept of controlled change, of managed damage. That maybe it's a better idea to identify designated spots to hang a bear bag, a designated spot to use the restroom. That once a campground is too worn it's shut down and a new one made.

This ties into making it easier to do the right thing. Better to put metal food boxes in defined campsites than have people hang bad and feed the bears.

And what about mice? Rodents carry disease such as hantavirus. We need to start talking about protecting mice from humans.
