Kalamazoo Nature Center Survey

 

Non-Vascular Plants

Methods
 
The entire property was surveyed for non-vascular species, except for the southern
fields that had been too recently disturbed to reflect accurately their typical vegetation.
Since most of these plants grow low to the ground, the search was conducted on and
under the leaf litter and near, on and under fallen trees, almost always off broken trail.
 
Two methods were used to inventory the three different types of non-vascular plants
studied: fungi, lichens and bryophytes. Fungi were identified on site using Mushrooms
Demystified (Arora 1986) when the criteria needed for identification were sufficiently
obvious. If a specimen defied field identification, it was placed in a box on an
appropriately colored piece of paper to obtain a spore print and taken into the lab to be
identified microscopically.
 
Bryophytes and lichens were collected in the field using Grout's method as outlined in
Mosses with Hand-Lens and Microscope, published in 1903. An appropriately sized piece
of moss found with complete setae, or a lichen in its natural state, was removed from its
place and put in a paper envelope marked with date collected, nature of the substrate
and its surroundings, approximate abundance of the species and location. Because it is
nearly impossible to identify bryophytes and lichens in the field, all samples collected
were taken back to the lab and identified under optical magnification.
 
 
Qualitative Non-vascular Plant Survey Results

 

General

The survey was conducted between 24 April and 30 September 2000. All three seasons
covered provided abundant samples of the non-vascular flora.
 
Fungi
The fungi identified (Table A) were consistent with the type of forest cover found at the
Asylum Lake Preserve. Oak conk, dryad saddle, scarlet cup fungi and many other
fungi were found and identified. The fungal flora was abundant.
 
Of particular interest was the species Coprinus micaceous, found in the Old Orchard.
Generally the presence of this fungus indicates burnt soil. It was abundant and found
throughout this sector. Though research was done to see if burning had occurred
before the orchard was planted, no evidence could be found. However, it is known that
Native Americans used fire as a management tool in some instances (Chapman 1984). It
was also common practice to burn an area before planting it with orchard trees, so this
indicator species could be evidence of an historic burning. Other supporting evidence
was the ubiquitous presence of mosses and a lack of higher vascular herbaceous
growth.
 
Mosses and Liverworts
Mosses are listed in Table B. Without independent validation of the identifications, the
potential exists for error, particularly at the species level. The extensive disruption of
the site over the past 150 years profoundly affects the nonvascular flora. The probable
influence of fire prior to the recent era also is relevant. For a few types, specimens with
setae, a critical feature for identification, were never found, so these remain anonymous.
No moss of particular interest was found. However, Dr. Elwood B. Ehrle of Western
Michigan University’s Department of Biological Sciences (Personal communication
2001) has provided a list of “bryophytes which might persist in seriously disrupted
places like the Asylum Lake property and other areas with depauperate woods, a
largely destroyed forest floor community and polluted wetlands.”

In addition to the above, Dr. Ehrle provided a list of bryophytes likely to occur at less
disturbed sites in Kalamazoo County. This list is not included in the report.
 
Lichens
The number of different lichen species (Table B) was notable.
 
Ferns
The small number of fern species present (Table B) reflects the disturbed nature of the
site.
 
Overall, the non-vascular flora is widespread and varies from diverse to depauperate,
depending on the group.
