Nope. For example, you missed:
A 2001 study performed by botanist Richard Reader of the University of
Guelph (Canada) noted that "We've found that hikers have the same
effect as bikers do, regardless of the number of trips along the path.
In reality, both are equally damaging to the environment, but there is
increased trail wear because twice the number of people are now using
the trails." (Impacts of Experimentally Applied Mountain Biking and
Hiking on Vegetation and Soil of a Deciduous Forest - Eden Thurston
and Richard Reader).
as well as:
Perhaps the most widely accepted research on trail impacts of
different users is the Seney/Wilson Study as it compared all the user
groups together in one study (hikers, motorcycles, mountain bikes, and
horses). Some of the findings from the Seney/Wilson Study include:
"The sediment yields reported in part B of Table 4 indicates that
horse plots produced significantly more sediment yield than the
bicycle, control, or hiker plots." "Hiker and bicycle plots were not
significantly different from each other or the control plots." "
Indeed, hikers produced the second largest increase in sediment yield
following the horse treatments, and overall the horse and hiker plots
suggest that hooves and feet make more sediment available for removal
than wheels on pre-wetted soils. The results in Part D of Table 4
indicate horse traffic produced significantly more sediment than other
users on dry plots as well". (Erosional Impact of Hikers, Horses,
Motorcycles, and Off Road Bicycles on Mountain Trails in Montana- John
Wilson and Joseph Seney - Mountain Research and Development 1994)
It's obvious that you don't know how to read.

Except when the so-called "research" LIES, and the review tells the
truth, as I did.
