[Talk-us] National Forests and Private Ownership

It isn't just privately held lands. U.S. DoD has numerous inholdings ( DOD
owns 11.4 million acres in the United States, with individual parcel
ownership ranging from 0 acres owned to 2.3 million acres  ), FAA for nav
aids, I believe there are also instances of tribal lands ( Bureau of Indian
Affairs (BIA), the U.S. holds approximately 56.2 million acres in trust for
various Indian tribes and individuals.  ). For instance, the Department of
Energy ( 'Better Bombs for a Better Way of Life' ) ... " DOE is the fourth
largest federal land manager, conducting its mission at 50 major sites on
2.4 million acres across the country."

And size is no determination of importance, because the 'rules' are
dramatically different for different agencies and departments. Some of
these provide access, The Magruder Corridor easement is basically the width
of the track, between two wilderness areas, similarly various boat landing
on lakes etc. Other very small areas, which have VERY nice gravel roads
leading to them, will result in an armed response. "There have been 12
Minuteman missile sites constructed on the ( Pawnee, Forest Service ) )
grassland. These fenced areas (approximately two acres each) are  US Air
Force and public access is not permitted."

Once again, I deal with what I think is an exact parallel in New York. If
there's a public-access easement on private land, I outline the easement or
map the trail and put the appropriate access constraints (and
boundary=protected_area+protect_class, if appropriate) on it.

I haven't done very many of these for want of reliable data.  One set that
I have done is that there are a good many public-access lands in the
Catskill Mountains for which New York City's Bureau of Water Supply is the
'private' landowner. These are mapped (within the boundary=national_park of
the Catskill Park) as things like leisure=nature_reserve
boundary=protected_area protect_class=12 protection_object=water
access=private foot=yes. (There are other tag combinations, once again,
because there are regulations pertaining to specific parcels).

Sample situations:

Administrative border of the Catskill Park:
https://www.openstreetmap.org/relation/6265477

New York City public-access inholding within the Catskill Park:
https://www.openstreetmap.org/way/424227080 Note that the highway
right-of-way is a state-owned inholding within that. (The road is private
once you cross onto New York City lands and the gate is ordinarily locked
to prohibit motor vehicle traffic. They unlock it in the winter to allow
snowmobiles through)

One parcel of public-access land that the state owns in allodium (being
sovereign, the state does not hold in fee), within the park. Note exclaves
of this holding, plus private inholdings mapped by exclusion:
https://www.openstreetmap.org/relation/6367009

A single-purpose recreation area (again, state-owned, although privately
operated) within the Park, again with private inholdings:
https://www.openstreetmap.org/relation/6373343

A private inholding (untagged) within a Wild Forest area (one tier below
Wilderness), within the Catskill Park:
https://www.openstreetmap.org/way/428667447 within
https://www.openstreetmap.org/relation/6375713 within
https://www.openstreetmap.org/relation/6265477

A public footway mostly on public land, but with portions that cross
private inholdings: https://www.openstreetmap.org/way/286143201

What sort of thing am I failing to model here?

Once again, I think that New York state lands offer a parallel.

The administrative borders of the Adirondack and Catskill parks are mapped
(boundary=national_park protect_class=2). This has been discussed
elsewhere; for these two specific regions, national_park appears to be a
better fit than a mere protected_area.

The state-owned and -managed land within the regions is mapped as well.
boundary=protected_area protect_class=1b leisure=nature_reserve foot=yes is
one combination, but there is a whole zoo of land classifications with
different land use and access constraints.

The private inholdings are mapped only by exclusion.

As far as I understand (and tag), the owned lands should be tagged as
landuse (generally, landuse=forest, access=yes, operator=xxx National
Forest), but the administrative boundary is something different from
that. From what I see in parts of the SE (looking specifically at
Chattahoochee-Oconee, Nantahala, etc area), the administrative
boundary multipolygon is around *only* USFS owned lands. I would
consider this tagging style incorrect, and largely the exception
relative to the rest of the US.

Proclaimed boundaries are the administrative boundaries, and should be
tagged with "boundary" tags as they are in most of the US. Actual
owned land (fee owned) is a matter of landuse and should be tagged
using landuse tags. Unfortunately, this doesn't necessarily show
distinctly on the main OSM slippy map. However, this is a generic map
that is not *necessarily* designed to be useful for any one specific
thing, and trying to show different ownership of land can get messy
very fast. The data in the OSM database should reflect the distinction
between designated administrative boundaries and actual managed forest
land, regardless of whether this shows nicely on the slippy map.

If the goal is to see clearly what land is actually owned by the USFS,
then it is likely better to either use the USFS topo maps, or develop
your own map style that shows the difference!

The way may be, but usually the land itself is not. The land is still
tagged access=private, and the trail is tagged either access=yes if it
is a legal public easement over private land, or access=permissive if
there is an agreement with the landowner to allow public to access the
trail as long as they stay on trail (but there is no legal right of
way otherwise)

All,

I got this message off list from Greg Mathews who works for the USGS, for
some reason he was unable to post himself (something wrong with his
subscription perhaps):

BEGIN
Hi folks, This is a dataset I'm somewhat familiar with. Likely the best
available data for land management agency boundaries is from PAD-US here:
https://www.sciencebase.gov/catalog/item/5b030c7ae4b0da30c1c1d6de

Federal land management agency boundaries generally come in two types: 1.
Proclaimed boundaries - these are Congressionally mandated boundaries, and
2. Fee Owned - these are boundaries actually owned by the agencies and show
in-holdings, slightly different boundaries, etc. The Fee Owned is a a
subset of the Congressionally Mandated boundaries as someone else
explained. My unofficial suggestion is if you want to model recreation, it
would be better to show the Fee Owned boundaries so people don't end up on
private lands. The US Topo uses proclaimed at this time.

I understand and generally agree.  One point is that the NFS may have made
arrangements with the landowner such that some access by the public is
permitted.  I say this because an official USFS trail (Crosier Mountain

Another place to discuss this might be 
https://wiki.osm.org/wiki/Talk:United_States/Public_lands , an emerging place 
to try to unravel the highly complex multi-jurisdictional, part 
human-recreation (part not), "public lands" in the USA.  This wiki originally 
started from a multi-volunteer effort to try to better express semantics 
regarding "parks" — especially "state parks" and "county parks," somewhat 
nightmare-ish in OSM, but with greater understanding and many voices, perhaps 
many years from now, I believe these issues can be solved, if not better 
expressed than they are today.

The issues discussed, like inholdings, wilderness-OVER-forest (rather than 
subsets of) are what I and others here have mightily struggled with for over a 
decade, especially as good data (like USFS shapefiles and CPAD) have emerged 
and are available to us, AND update over time!  The topics (and concomitant 
tagging) are complex and not easy for OSM's tradition of wide consensus to 
agree upon.  Nonetheless, we should continue to strive to do our best.  I am 
heartened to see good discussion like this here.

Please know that when you ask such questions, and others (well-intentioned, 
intelligent, familiar with the topics and difficulties involved...) chime in, 
you walk into a very large space with seriously complex semantics.  OSM can 
(and will, I believe) better untangle these issues, but we must give ourselves 
the time and polite space for the many voices, points of view and deep 
knowledge we have to synthesize into how we best do this.  A good starting 
point is "this is difficult, there are widely differing points of view, there's 
a lot of history in OSM and new schemes have emerged while older data remain in 
the map."  See, that right there is a lot to chew on!  There are likely 
multiple ways forward, really.

Every National Forest has an administrative boundary - they can be
downloaded here:
https://data.fs.usda.gov/geodata/webapps/EDW_DataExtract/. Accept the
disclaimer, click the button with the scissors in the top left corner,
choose the national forest you want, select 'Administrative Forest
Boundaries' (preselected), choose your file format, and open in your
favorite GIS program. This boundary is what is in OSM, or at least
what should be. These boundaries can also be viewed using USFS Topo
maps (https://data.fs.usda.gov/geodata/rastergateway/states-regions/states.php)

You will see that sometimes private land punches a hole in these
boundaries, and if so it should be in OSM as such. But you will also
see that sometimes (often times in the west coast), private land
*doesn't* punch a hole in the boundary, and thus there *shouldn't* be
a hole in the boundary in OSM despite being a private in-holding. This
is what I mean by these conflating landuse and jurisdiction. Private
land inside NF boundaries does not automatically mean there's a hole
in NF boundary.

Please do not add holes in the boundary unless they are officially
designated! Otherwise there is no point to keeping these
administrative boundaries in OSM.

It depends on what is actually on the ground. It appears you and
others are conflating jurisdictional boundaries with
landuse/ownership. While NF-owned land must be within a NF boundary,
that is the end of any relationship between NF boundaries and
on-the-ground landuse. The "National Forest property behind this sign"
demarcates landuse, not jurisdiction. For example, in theory, there
could exist a single parcel of private property, that is also
partially within a designated wilderness, that also spans across two
different national forest boundaries. There's no casual relationship
between these concepts, in the sense that "this land is private,
therefore it is a 'hole' in the NF boundary".

What is actually on the ground should be tagged using landuse.
Private forest cabin within NF? landuse=residential, access=private.
Tree-covered land owned by USFS? landuse=forest, access=yes,
operator=Tahoe National Forest.
Private timber harvesting land? landuse=forest,
access=private/permissive, operator=whoever.
Notice that none of these involve changes to anything 'boundary',
because they're distinct and (mostly) orthogonal concepts.

The NF boundaries, for the most part, are correct in OSM as they are
and should not be touched unless incorrect per USFS GIS data which is
the reference for them. It's difficult to notice when they've been
incorrectly changed, and it's even more difficult to fix them once
they have been messed up. Someone has made up a lot of work in
California a few years ago by making wilderness boundaries share ways
with NF boundaries (mutually excluding NF jurisdiction from wilderness
area), when in fact wilderness areas *overlap* NF jurisdictional
boundaries and do _not_ exclude them (ie, wilderness areas are often
managed by multiple National Forests, and are not their own
separately-managed entity). I have fixed a couple near Lake Tahoe, but
it is enormously time consuming work that requires some experience
with GIS tools as well as JOSM, which is very frustrating considering
they were correct in the first place.

Bradley,
I'm not sure that this is typically how federal lands are conceptualized,
at least on the east coast.  It is usually as Mike suggests a 1:1
correspondence with the actual Fee Simple boundary and federal management.
A lot of times when maps are drawn or gis data is developed scale is a
consideration and just conveying where a National Forest is is more
important than showing a patchwork of in-holdings (which by the way are
constantly changing with land swaps and selling or buying parcels). This
may be where the idea of an administrative boundary or area comes from? In
any case a really excellent source for all protected lands is the USGS
PAD-US dataset.
https://www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/protected-areas

Disclaimer: I am the Georgia data steward.

So Mike,
I would say if you have the information and data that there's a private
in-holding, I would exclude it from the National Forest (or whatever)
polygon and maybe map the landcover (forest, etc) if you are so inclined.

The consensus of those who replied seem to be to exclude these privately
held lands from the National Forest boundaries.  Is that correct? Does
anyone object to that approach?  If not, I will proceed in that manner as
well.

Land actually owned and operated by the USFS is always a subset of the
jurisdictional boundary of a given NF. Near where I live, half of the
entire city of Reno is within the Humboldt-Toiyabe boundary, the
entire city of South Lake Tahoe within LTBMU, town of Truckee entirely
within Tahoe NF, etc. The jurisdictional boundaries are more or less
unhelpful in determining whether land is managed by the USFS or not.
I'm assuming this must not be the case in other parts of the country,
where the vast majority of the land within a boundary can assumed to
be owned by the USFS?

Aside from surveying boundary markers (which are inconsistently placed
and would be a logistically impossible task), the only other ways to
know what land is actually owned by the USFS is to check county parcel
data, or use the 'Surface Ownership' gdb/shp available using the USFS
Data Extract tool. In CA, we are very lucky to have the CPAD database,
which compiles the majority of public/semi-public lands into one
database, updated yearly, and free to use (see Contributors page in
OSM wiki). Where these lands also have tree cover, I tag them
'landuse=forest' and 'access=yes'. Any private "inholding" gets tagged
for what it is.
