We investigated the nesting and feeding habits of Cassowaries in two areas from Utsunomiya City to Haga County and near Kanuma City, Tochigi Prefecture, and analyzed
the relationship between environmental factors and the number of nests. The study area was divided into a mesh of approximately 2 km, and multiple regression analysis
was conducted using the number of nests as the objective variable and environmental factors such as vegetation and population as explanatory variables, yielding a
model with an adjusted coefficient of determination of R2'=0.727. The results suggest that the combination of rice paddies and slope forests in the valley and their
continuity is important for the nesting of the rustler's hawkbill.

The utilization and conservation of nature is considered an important issue in the development of parks, and for this purpose, evaluation and planning based on an
understanding of the distribution of natural resources and an ecological understanding are considered necessary. However, in large parks and woodlands, information on
the distribution of forest floor plants is rarely available for a large number of species over the entire area. Therefore, we analyzed and predicted the suitable
growth areas of forest floor plants using the relationship between plants and the environment, and examined the possibility of using this information as basic
information for the development and conservation planning of green spaces.

When using a park in a satoyama hillside area rich in nature, it is essential to balance the use of the park with the conservation of biota, and it is necessary to
properly identify areas suitable for use and those in need of conservation. Therefore, in this study, we attempted a comprehensive evaluation of the environment using
two axes, ecological richness and convenience, using the National Michinoku Morinokohan Park Phase III area as a case study site. As a result, we were able to
classify the case study site into four categories: conservation-type management, development-type use, development-type use - conservation-type use, and
conservation-type use.

Relationship between Forest Management and Blooming Status of Forest Floor Plants in Michinoku Morino Lakeside Park
Year Published:2005
Author:Yoriko Hatase・Fujiwara Nobuo・Hitomi Oguri・Hiroshi Momose・Etsuko Utsugi・Eizo Oe・Ikuko Inomoto
In park forests used for walking and other activities, it is necessary to maintain a forest floor vegetation suitable for use. A variety of forest floor vegetation
grows on the forest floor in thickets, depending on the management conditions. However, in thickets that are abandoned due to infrequent use, the forest floor becomes
darker due to the overgrowth of sassafras and shrubs, and the number of flowering plants on the forest floor decreases, the number of species decreases, and the
composition of species changes. Therefore, appropriate management is necessary to maintain a forest floor vegetation suitable for use. In this study, we conducted an
experimental forest management in Michinoku Morinokohan Park in the Tohoku region, where there have been few studies so far, in order to examine management methods to
restore diverse forest floor vegetation and to promote flowering of forest floor plants. The results of this study are as follows.

Phenology of Wetlands and Ryukinka Leaves Developed on the Bottom of a Small Valley on a Hillside in the Kamabo District, Miyagi Prefecture, Japan
Year Published:2005
Author:Megu Ueno・Takao Kikuchi・Nobuhiko Wakamatsu・Masahiko Matsue・Hitomi Oguri・Yoriko Hatase
In the Kamabo area of Miyagi Prefecture, we found a small valley where wetlands had developed on the valley floor due to the loss of catchment area caused by river
strife and thus the loss of erosive power. Since this nature of rhizomatous leaves has not been previously known, we conducted an investigation to clarify the
morphological and ecological characteristics of rhizomatous leaves before and after the flowering period and the role of the leaves after the flowering period. As a
result, it was concluded that A. ryukinka is a plant that produces new rhizomatous leaves almost all year round and remains evergreen, replacing its leaves several
times a year, although its size changes depending on the season and environment.

Seed dispersal, which has important implications for the meta-population dynamics of Kawaranogiku, is unknown. Therefore, we examined seed dispersal in a restored
population in the Nagata area of the Tama River. Seeds were dispersed mostly downwind of the prevailing wind during the dispersal period, but were also dispersed in
the upwind direction. The number of seeds dispersed by the wind was higher at lower heights from the ground, and most of the seeds flew lower than the general
community height of the tall-stemmed herbaceous community. In addition, scattered seeds were concentrated in gravels, especially where there were many glue stones and
floating stones. The maximum dispersal distance in wind dispersal estimated from the emergence position of seedlings was 250 m, which was longer than the previously
estimated distance of 30 m. Seedlings were produced by wind-dispersed seed dispersal on the newly formed round stone riverbanks.

Historical image analysis of cityscape based on grain theory
Year Published:2005
Author:Tsuneaki Fukui・Osamu Fujiwara
The purpose of this study is to clarify the conditions of a street that gives a historical impression by introducing grain theory, which considers roadside elements
of a street, such as stores and residences, as grains. As a result of analyzing the relationship between the historical impression evaluation and the grain
composition ratio obtained from experiments on historical streets, the following conclusions were obtained: 1) the historical image of a street is strongly correlated
with the grain composition ratio, and the application of grain theory to the analysis of street image is effective; 2) in order for a street to be evaluated as having
a sense of historicity, it must have a historical facade; 3) the historical facade of a street must have a historical character; and 4) the historical facade must
have a historical character. 3) We proposed an equation to predict the historical impression of a street based on the grain composition ratio, and proposed a measure
to increase the historical evaluation of a street through this equation. The proposed measures to increase the historicity rating of a street through this formula are
as follows.

A Study on Post-evaluation of Landscape Improvement Projects - Case Study of Sakai River, Urayasu, Japan
Year Published:2005
Author:Sota Aniya・Tsuneaki Fukui・Osamu Fujiwara
The number of landscape improvement projects is expected to increase in various regions in the future, and there is now a need for a system to evaluate the
effectiveness of such projects and to make the best use of the results in the next phase of projects. In this paper, we propose a framework for ex-post evaluation by
organizing evaluation items and procedures for landscape improvement projects that mainly aim to have an effect on the daily lives of residents, and conduct a case
study focusing on “activity change” among the three effect manifestation stages mentioned in the framework. In this case study, we first summarized the planning and
design intent of the residents' activities, then grasped the effect of maintenance three-dimensionally through the investigation of activity change, and finally
evaluated the project to see if the intended effect was achieved by comparing the results of the investigation. In addition, we were able to extract useful
information for future planning and design, such as the occurrence of events in the maintenance section, which showed that the effects of the project were greater
than intended. Through this case study, we were able to confirm the importance of ex-post evaluation focusing on the daily lives of residents.

Timing for the planting method using deciduous forest topsoil in suburban Tokyo, Japan
Year Published:2006
Author:HOSOGI Daisuke, KAMEYAMA Akira
The suitable time for planting using the topsoil of a warm temperate deciduous forest is discussed based on the germination characteristics of the soil seed bank.
Forest topsoil was collected regularly over a 1-year period from a deciduous forest in suburban Tokyo, and seedling emergence in the outdoors was recorded immediately
after collection. Many seedlings were observed from February to May, indicating that this is the best time for planting because this is when most buried seeds
germinate. Additionally, it was inferred that buried seeds germinate immediately after planting during the period from February to October, although the quantity of
seed germination varies according to the season. The method of evaluating the forest topsoil as a planting material is also discussed. The simple and preferred method
of evaluation is to examine outdoor seedling emergence from February to May. Accurate evaluation during the summer and autumn months proved problematic, especially
when counting tree seeds, and it was necessary to continue the evaluation into the following spring. A practical understanding of the timing of planting and the
method of evaluating forest topsoil as a planting material is possible in warm temperate areas.

Study on the spreading thickness, fertilizer amount, and mulching for forest topsoil revegetation on embankment slopes.
Year Published:2006
Author:Daisuke Hosogi・Sotaro Yonemura・Shou Kameyama
We focused on the spreading of topsoil, which is the simplest method among the forest topsoil revegetation methods, and conducted experiments to examine the spreading
thickness, fertilizer amount, and mulching effect when spreading the topsoil. As a result of measuring and comparing the number of germinating and surviving
individuals, coverage, and the number of emerged seeds, it was considered that a spreading thickness of 4 cm or more, 200 g of slow-release fertilizer equivalent to
N:P:K = 10:18:15, and mulching with straw mulch would be effective as a method of construction. When using topsoil with a high enough density of buried seeds, it was
also considered that mixing the topsoil with growth foundation material and spreading it out thickly would be effective in promoting the growth of buried seeds after
germination while saving the amount of topsoil used. As for fertilizers, it was considered that a slow-acting fertilizer with a long-lasting effect for several years
or more should be used in combination with a relatively fast-acting fertilizer.

Cut slope revegetation using natural plant dispersal from above forest in Tochigi, Japan
Year Published:2006
Author:HOSOGI Daisuke, NAKAMURA Katsue, KAMEYAMA Akira
We examined a revegetation method for cut slopes in forests using natural plant dispersal from the surrounding vegetation. Six plots in a cut slope on bedrock
(inclination: 68°, aspect: S45°E, 150 m above sea level) in Tochigi, Japan, were treated with various types of netting and fertilizer. We surveyed the plant
communities, individual trees, and seed rain on the cut slope, and the plant community on the undisturbed upper slope. Coverage ratios of fertilized sites were higher
than non-fertilized sites in every year. Coverage ratios of fertilized sites exceeded 40% after 5 years; in contrast, coverage ratios of non-fertilized sites were
approximately 10%. We concluded that the application of fertilizer was essential for the success of this natural revegetation method. The revegetation method using
biodegradability netting with fertilizer and water-retention material was the most effective. The resulting plant community consisted of 29 species/5 m2, including
seven tree species with a density of 21.6 trees/m2. The five species with the highest summed dominance ratios (SDR2) were Miscanthus sinensis (perennial herb),
Clethra barbinervis (tree), Lepisorus thunbergianus (fern), Dryopteris erythrosora (fern), and Pinus densiflora (tree).

regression analysis was conducted using the area of the estimated nesting area of the goshawk within each mesh as the objective variable and environmental factors
such as vegetation and population as explanatory variables. The results showed that the length of the forest-grassland adjacency, which had a particularly high
contribution rate, was considered to be an indicator of an environment in which goshawks have easy access to food.
