planning. B.Sc.F Thesis, Faculty of Forestry and Environmental Management,
University of New Brunswick.
The objective of this paper was to determine whether corridors
are an appropriate conservation measure for New Brunswick. Empirical
evidence indicates that species use corridors for movement and for
habitat, and that corridors increase both migration and survival
rates. Forestry practices in New Brunswick are fragmenting the interior,
old and unique forest types. The species that are vulnerable are
interior habitat specialists with low mobility (plants, amphibians
and small mammals). Corridors are put forward as a means of conserving
biodiversity in a multiple-use landscape by reconnecting the forest
and preserving the flow of wildlife in a changing environment.

Thesis, Faculty of Forestry and Environmental Management, University

Fifteen stands were located within 15 km of Fundy National
Park (FNP). Three reference stands with a disturbance regime of
spruce budworm were located in FNP. Managed forests were identifed
on crown land. Structural variability among age classes within the
same disturbance type and among similar-aged stands of different
disturbance types were examined. The comparisons of density, dbh,
height, basal areas, and crown lengths of both live and dead stems
were designed to show the effects of time on structural variability.
Results revealed that snag densities may be negatively correlated
with diameter and height.

of woody plant species in the Greater Fundy Ecosystem, New Brunswick,

Surveys of woody vegetation, snags, and coarse woody debris
(CWD) were conducted on 20 study sites located in and around FNP.
Tree-sized snags were lacking in most of the plantations. Shrub-sized
snags accounted for most of the total snag density on plantation
sites. Reference (mature) stands had twice as many tree-sized snags
as shrub-sized snags. The highest CWD density and biomass occurred
in the youngest plantations. However, CWD of any size category was
almost completely decomposed after about 13 years of plantation
establishment. Total CWD carbon stored in reference stands was greater
than in plantations older than 5 years.

The northern flying squirrel (Glaucomys sabrinus (Shaw))
was studied in southern New Brunswick from May 1993 to November
1994. Home range, habitat use, and nesting ecology were examined
using radio telemetry. Diet was determined through faecal analysis
and observation. Median size of home ranges determined for eight
female and seven male northern flying squirrels were 2.75 and 12.49
respectively. Within home ranges, high use sites had significantly
larger trees, larger snags, lower density of trees, greater structural
diversity, and a more decayed structural composition than low use
sites. Four distinct nest types were identified: ground, outside,
natural cavity, and woodpecker. Microscopic examination of 150 faecal
samples revealed that 95% contained hypogeous fungal spores.

forest in the Hayward Brook Watershed, New Brunswick. B.Sc. Honours
thesis, University of New Brunswick (Saint John).
This study provides baseline data for a long-term study
on the effects of forest management practices on diversity of the
herbaceous community. Community structure of the herbaceous vegetation
in the Hayward Brook Watershed was assessed using 169 5-m2 quadrats.
One-hundred and six species were present. Species evenness was low,
i.e. 80%of the species occurred in <20% of the quadrats.
Canonical correspondence analysis showed that 24% of the species
pattern captured by correspondence analysis was correlated with
the environmental variables chosen in this study (canopy, topography
and litter). Partial canonical correspondence analysis was employed
to partition out the individual and combined effects of the environmental
variables; litter chemistry (particularly pH, and Ca and Mg contents)
was the most highly correlated with species pattern.
Changes in community structure after catastrophic disturbance were
predicted using both equilibrium and non-equilibrium models; these
will be tested as the study continues, in order to better conserve
biodiversity of the forest floor.

Responses of forest bird communities to the conversion
of mature, mixed-wood forest into even-aged conifer plantations
were studied in the vicinity of Fundy National Park. Clearcutting
of mixed-wood forests and establishment of young plantations created
opportunities for some bird species of open-canopy habitats, while
destroying habitat for birds of mature forest. It is anticipated
that some bird species may not be accommodated in intensively managed
working forest. At risk are species dependent on snags, coarse woody
debris, or cavities as critical elements of habitat, forest-canopy
species requiring a significant deciduous content, and species requiring
large-dimension trees.

Species and location of 3880 witness trees were obtained
from land survey records (1785-1820) and 957 Forest Development
Survey Plots (1986 and 1993) were analyzed in Kings County, N.B..
The frequency distribution of species and genus levels for pre-settlement
and present-day surveys were calculated and compared per ecosite
for each genus that made up more than 5% of the total composition
of the pre-settlement or present-day ecoregions of Kings County.
Over the past two hundred years there has been a shift in species
composition away from the late successional species. Human disturbances
such as land clearing for agriculture, forestry, and budworm suppression
are likely to be the primary factors in such changes.

fine scale variability for predicting sampling intensity in a mixed
temperate forest seed bank. B.Sc. Honours thesis, UNBSJ.
A variety of factors cause seeds to exhibit clustered
distributions or low abundances in the soil. This has important
implications for seed bank studies that require an accurate estimate
of species richness and species abundance, especially in terms of
sampling intensity. This study was undertaken to determine the fine-scale
horizontal spatial distribution of seeds in a soil seed bank in
a harvested temperate forest at Hayward Brook, New Brunswick, Canada
and to determine the minimum sampling intensity required for an
accurate representation of seed bank species composition. By completely
sampling the topsoil of a 2.46m2 experimental plot in 384 units
of 50.27 cm2 (volume 170.9 cm3), and using the emergence method,
eight taxa were germinated from the samples. Red Maple (Acer rubrum)
showed the higherdf samples, probably >100, representing at least
one-fifth of the area, would be needed.

New Brunswick: Fundy National Park. Canadian Forest Service, Fredericton,
19 p.
The Spruce Budworm Decision Support System Protection
Planning System (PROPS) was implemented on the Fundy National Park
(FNP), a total landbase of 19,356 ha. The FNP landbase is composed
of 18,387 ha of productive federal forest. PROPS predicts the budworm-caused
volume losses, or alternatively the marginal timber supply benefits
of protecting stands against spruce budworm defoliation in a given
year. Because there was no quantifiable budworm defoliation on the
FNP during the past 5 years and no predicted 1999 budworm populations
from larval surveys, actual budworm losses in 1999 were 0 throughout
the landbase. In other words, with no expected defoliation in 1999,
there would be no mortality or growth reduction. The various tables
and maps in this report allow the evaluation of potential volume
losses that would be caused by a budworm outbreak on FNP. A “normal”
severity budworm outbreak, similar to that experienced in New Brunswick
in the past, was estimated to result in 252,000 m3 of mortality
and growth reduction.

recolonization in a mixed forest in New Brunswick. M.Sc. thesis University
of New Brunswick, Saint John.
This study examined disturbance characteristics resulting
from forest harvest and associated changes in bryophyte species,
the ability of two bryophyte species to tolerate the environmental
conditions that result from forest harvest, and the species composition
of the bryophyte diaspore bank in the Hayward Brook watershed.
- Different suites of disturbance characteristics were associated
with specific forest practices, i.e. cutting and scarification. Whereas
clearcutting removes tree canopy, thereby altering the microclimate,
subsequent scarification redistributes slash and disturbs the litter
and soil substrates, increasing the intensity of disturbance. At the
quadrat scale, individual disturbance characteristics occur in all
treatments (uncut, cut, and cut and scarified), however their occurrence
increases in frequency with harvest intensity.
Bryophyte community composition immediately after harvest
is more strongly related to pre-harvest bryophyte composition than
to disturbance variables, however loss of species from the community
is more prevalent with the combination of cutting and scarification.
Transplant experiments showed that both Dicranum polysetum and Pleurozium
schreberi were able to tolerate the environmental conditions that
commonly occur during and after forest harvest for at least two
years. The amelioration of environmental extremes that is provided
by light slash cover proved beneficial to Pleurozium but not Dicranum.
Both species exhibited greater final weights on mineral substrate
than on humus, which is at least partly due to increased inorganic
uptake from mineral substrate.
A diaspore bank of at least 25 bryophyte taxa exists in the soil
of the Hayward Brook area, but its species composition is very different
from that of the pre-harvest vegetation. There is no apparent relationship
between stand treatments (uncut, cut, and cut and scarified) and
the species composition of the diaspore bank. The diaspore bank
is a potential source for recolonization after forest harvest, but
it is unlikely to result in reassembly of the same pre-harvest bryophyte
community.
- Ross, Amy. 1999. Forest floor bryophyte composition of spruce plantations
in New Brunswick. B.Sc. Honours thesis, University of New Brunswick,
Saint John.
Modern forestry has been identified as a serious threat
to many forest species, particularly invertebrates and cryptogams
such as bryophytes. Fifteen stands (6 field-origin plantations,
i.e. plantations established on land that had previously been used
as an agricultural field, 7 forest-origin plantations, and 2 naturally
regenerating forests) were sampled within the province of New Brunswick
to determine the status of forest floor bryophyte diversity in spruce
plantations relative to natural forests. Both (i) species composition
and (ii) attributes of the structural environment were measured
in each stand as percent cover in 40-50 1m2 quadrats set on parallel
transects. Multivariate analyses showed that both (i) species composition
and (ii) environmental characteristics differed significantly among
three stand classes (i.e. field-origin plantations, forest-origin
plantations, and natural forests). Species richness, evenness, andtenvironmental
features were not strongly correlated with the variability in species
data. This suggests that bryophyte diversity is not predicted by
habitat features, indicating that forest management efforts which
focus on habitat conservation (e.g. retention of hardwoods in otherwise
coniferous monoculture and CWD in various decay stages) may not
be as effective in maintaining bryophyte biodiversity in managed
landscapes as previously thought.

Temperate Forest. B.Sc. Honours thesis, University of New Brunswick

Bryophyte community structure may be influenced by underlying
environmental factors at various spatial scales. What proportion
of the observed bryophyte species distribution pattern is directly
attributable to environmental variables? Within the Hayward Brook
Watershed (Westmorland County, NB), bryophyte species abundance,
canopy, litter and topographical variables were recorded in 155
1.25-m2 quadrats. Partial Canonical Correspondence Analysis (PCCA)
was used to partition out the individual and combined influences
of environment on species distribution. Environmental variables
accounted for 26% of the total species pattern (3.564 of the 13.641
total inertia). Of the environmental variables, the unique contribution
of litter accounted for the largest proportion of the species distribution
pattern (14.3%), followed by topography (7.72%); canopy alone accounted
for the least (1.71%). The remainder (1.99%) was attributable to
combinations of these variables. Litter may influence bryophytes
in several ways: (1) physically, e.g. acting as substrate or barrier,
and/or (2) chemically, as a source of e.g. nutrients or toxins.
The remaining 74% of species pattern may be influenced by factors
such as other environmental variables, interspecific relationships,
spore/gemmae dispersal and establishment, or chance.

(L.) S. Gray following dessication. B.Sc. Honours thesis, University
of New Brunswick (Saint John), Submitted to The Bryologist October
1999.
Bazzania trilobata (L.) S. Gray is a common leafy liverwort
on the floor of closed canopy mixed and coniferous forests in New
Brunswick. It may be a suitable indicator of bryohyte diversity
depending on its ability to adapt to forestry-related environmental
stresses, however published information regarding this species is
scant. This study uses a combination of approamollected from a clear-cut
area adjacent to the forest, where they had been field-dried for
2 years. Baseline data were recorded for all samples as well as
for fresh samples (controls). All samples were subjected to a recovery
period of high humidity, low light intensity, and moderate temperatures.
Post recovery measurements were compared to the base-line data.
Metabolic activity, including net carbon gain, of the field-dried
samples increased following the recovery period, suggesting that
they are able to remain viable for at least 2 years following a
clear-cut forest disturbance and ultimately recover. Metabolic activity
did not increase for sun-dried and shade-dried samples following
the recovery period, suggesting the dessication tolerance range
of B. trilobata lies between the conditions of the clear-cut and
those of the sun-dried and shade-dried treatments. None of the samples
from drying treatments reached the photosynthetic rates of the controls,
before or after recovery.
Given its easy visual identification and sensitivity to dessication,
B. trilobata may be a practical indicator of a specific range of
environmental conditions associated with closed forest communities.
It may be useful in determining which forest-harvest technique causes
the least change to these conditions, with the ultimate goal of
maintaining native biodiversity, but further work is needed to determine
its ability to represent the status of other species.
- Waldick, R. 1994. Implications of forestry-associated habitat conversion
on amphibians in the vicinity of Fundy National Park, New Brunswick.
M.Sc. thesis, Dalhousie University, Halifax, N.S. 177p.
The effects of the conversion of a natural, mixed-species
forest in Eastern Canada into a managed conifer plantation was examined.
The ecological conversion resulted in changes in microclimate and
physical habitat that reduce the suitability of these sites for
some species of amphibian. At the stand level, increased exposure
occurred as a result of: tree canopy removal, and degradation in
the quantity and quality of leaf litter, and large-dimension woody
debris. Of the various species studied, only the American toad (Bufo
americanus) appeared to be tolerant of these habitat changes. Conversely,
the greatest influences were on the red-backed salamander (Plethodon
cinereus) and the yellow-spotted salamander (Ambystoma maculatum).
Although certain elements of plantations become more suitable foe
some amphibian species with time, the persistence of reduced relative
humidity and degraded litter quality limits other species. Furthermore,
recolonization by amphibians is also influenced by the juxtaposition
of silvicultural and natural areas over the landscape. The proximity
to mixed-species forests for immigration is particularly important.
The presence of amphibians at breeding habitats may not reflect
the status of local populations or the quality of the surrounding
habitat. Consequently, terrestrial species, like Plethodontid salamanders
should be used as indicators of habitat quality. Management efforts
should focus on mitigating changes to habitat features that influence
the most sensitive amphibian species (i.e., red-backed salamanders).
This can be accomplished by permitting sites to regenerate a variety
of tree species and retaining natural forests (large enough to support
viable amphibian populations) within plantations would ensure the
presence of source populations for recolonization.
