Chapter 2: LAND USE CHANGE FROM 1978 to 1998 |
| |
|
SUMMARY |
| |
|
There are 335,961
acres (525 square miles) of land and water in Antrim County. A study
performed by the Land Information Access Association (LIAA) indicated
that 24.2% of the total area (81,226 acres) had undergone a land use
change between 1978 and 1998. Much of the information in this section
is taken from the LIAA study. |
| |
|
Figure 2-1 shows
which land uses had the most pronounced changes. Figure 2-2 compares
the land uses between 1978 and 1998. |
| |
|
Some land use
changes between 1978 and 1998 are in the same general land use
classification. This includes about 42 square miles or 27,025 acres of
land. For example, an Urban use may have changed, but it changed to
another kind of Urban use; or a Forest use changed (or grew) into
another kind of forest and thus remained in the Forest use category.
Figure 2-3 summarizes the changes within a particular land use
classification between 1978 and 1998. |
| |
|
The amount of land
that changed from one classification to another during this twenty year
period was 55,890 acres or 87.3 square miles. This represents
approximately 16.6% of the total land and water area. |

URBAN and Built Up:
(Where
development has and is occurring...) |
| |
|
The Urban and Built
Up land use category includes uses that are related to human activity,
except agriculture. This includes houses, businesses, factories,
airports, utilities, and recreational grounds, such as athletic fields
and campgrounds. Cemeteries are also in this category. |
| |
|
In 1978, there was a
total of 16,070 acres in this category. According to the LIAA study
8,258 acres were added to this category from 1978 to 1998, while 224
acres changed from one Urban use to another Urban use. Interestingly,
there were 337 acres that changed to a use that was Non-Urban: 45.7%
became classified as Grass, 25.2% became Agriculture, 24.4% became
Forest land, and 16% became classified as Wetland. |
| |
|
As of 1978, 4.8% of
the County was in the Urban and Built Up category. At the end of the
20-year period of the study, 7.3% of the County had this
classification. This increase equals 8,258 acres or 2.5% of Antrim
County: 44% came from the Grass and Shrub classification, 25.2% came
from Agricultural lands, 24.4% came from Forest land, and 16% came from
the Wetland classification. |
| |
|
In Antrim
County two thirds of Urban Use changes are stemming from Grass
and Forest uses, while one-third came from Agricultural uses.
The major changes to Urban use are summarized in Figure 2-5.
Most of converted acreage (6,660 acres or 80.4%) was
classified to a subcategory use under Urban, titled Single
Family/Duplex. It is assumed that most of this was for single
family residences. The two thirds of the 6,660 acres that
became Single Family/Duplex are broken down by township in
Figure 2-4.
These
townships represent where the larger Urban use growth areas
occurred in the County during the period of study. |

There were small use
changes to business and industrial during the twenty-year period. Of the
8,258 acres converted to urban use, only 57 acres were converted to the
sub category of Commercial, Services, and Institutional uses. In
addition, only 135 acres were converted to Industrial uses. This
pattern may have some bearing on the employment needs in the county.
Antrim County seems not to be a place that one both lives and
works. |
| |
|
As stated, 6,660
acres changed to Single Family/ Duplex use from the period 1978 to
1998. In the period of the Census count, from 1980 to 2000, the county
population gained 6,916 persons. |

| |
|
The major loss of
Agricultural uses in the County is not to Urban uses, most of it is a
conversion of Grass and Forest uses. Of the Agricultural uses that
changed to other uses, 84% converted to Grass and Forest uses,
see Figure 2-6. This would indicate a loss of farming activity
resulting in previous farmland being allowed to return to a natural
state. Additionally, Urban uses from Agricultural uses converted 15.5
%. Most of the Urban growth came from previous Grass and Forest uses. |

Jordan, Banks,
Mancelona, and Milton Townships also had the larger changes to Urban
uses. |
| |
|
There were also
changes in use to Agricultural uses. About 5,500 acres of new
Agricultural uses were observed between 1978 and 1998. Most of this
change, 98%, was from Grass and Forest uses. Nearly half of the change
from Grass to Agricultural was in the following townships: Forest Home,
769 acres, Echo, 488 acres, Central Lake, 481 acres, and Helena,
380 acres. This may indicate a modest increase in farming type
activities in these townships. |

GRASS AND SHRUB
LAND:
(Where non-forested undeveloped areas are located...) |
| |
|
There was a large
change in the County in the Grass and Shrub Land classification. There
was a net change of 15,986 acres (see Figure 2-7) to other uses from
Grass and Shrub Land. Approximately 72% or 21,344 acres changed to
Forest uses. An additional 4,359 acres was converted to Agricultural
uses. Urban growth comprises 3,809 acres of formally Grass use areas.
As it was previously noted, 44% of the change to Urban uses came from
Grass uses. There was, however, a large gain of grass acreage. |
| |
|
A total of 10,639
acres of Agricultural uses existing in 1978 became Grass use by 1998. A
lesser amount, 2,871 acres, was created from previous Forest acreage.
Some of this may have come from timber cutting. |

|
The large change
from Grass to Forest is in part due to a natural process called
Succession. If an area were to begin with bare ground, there would be
an initial growth of plants on that ground that could survive under
those conditions. These plants would then begin to create conditions
that would be conducive to a next stage of plants. In Antrim County this
would be grass and low-to-the-ground broader leafed plants. Next, short
woody shrubs and bushes appear. These create conditions for larger
bushes and shrubs and then some fast growing softwood trees. As these
trees mature, they create conditions for larger, long-lived evergreens
and hardwood trees. This resulting forest, which often takes hundreds of
years to mature, continues, unless dramatically challenged by
environmental changes or natural disasters. This final condition is
called a Climax Forest or Climax Fauna. |
| |
|
The grass and shrub
acreage of Antrim County has become, for the most part, a young forest.
In the twenty-year period of the study, the County had a net loss of
15,986 acres of Grass uses. It gained, however, 19,974 acres of Forest
uses. |
| |
|
FOREST LAND:
(Where treed undeveloped areas are located...) |
| |
|
The County had a net
gain of Forest uses of 19,980 acres (see Figure 2-8). Most of this was
from the natural succession process from Grass and Shrub acreage. There
was also a gain of 4,496 acres from uses that were Agricultural in
1978. If both the Grass use loss and the Forest use gain are combined,
the County gained 4,003 acres of new natural kinds of areas. As noted
in the previous section, 4,359 acres of Grass uses were converted to
Agricultural uses. However, there was a conversion of 4,496 acres that
was in Agriculture uses 1978 to Forest uses in 1998. |
| |
|
Antrim County
continues to be forested county with over 180,000 acres of forested
land. This is more than half the area of the entire county. The
following eight townships contain 74.2% of the Forest use acreage in the
county: |

It should be noted
that all of these townships are east of the County seat, Bellaire. Only
one township located west of Bellaire, Banks Township has a comparable
amount of Forest uses totaling 11,819 acres. The forested lands are a
highly valued natural resource. |

WATER AND WETLANDS:
(Where
significant features are located...) |
| |
|
In both the Water and Wetland categories, there was a small gain in
acreage. Antrim County gained
113 acres of Water and 130 acres of Wetlands. It is not clear from the
LIAA data the source of this additional acreage. It may relate to the
amount of accumulated precipitation up to 1998 as compared to the
beginning of the study in 1978. It may also be related to the time of
year the land use data was collected or to construction of various
kinds, such as large buildings, roads, marinas, and lake/river
enhancements that created additional water areas or wetlands. It may
also represent awareness on the part of the people of the county to keep
the Water and Wetland areas safe from unreasonable intrusion. |
| |
|
Jordan Township during this period gained 38 acres of water, but lost 66
acres of wetland area.
Echo Township gained 54 acres of wetland. There is not a clear pattern
suggested by the data.
The County gained a total of 243 acres of water and wetlands during this
twenty-year period. |
| |
|
IMPLEMENTATION:
(What
should be done next?) |
| |
- Commission a
new aerial land use study and compare the findings to the 1978
and 1998 results.
