ENR 3300 Final Exam With Accurate Solutions
T or F. Species loss and deforestation are highly correlated with human populations; as
human populations increase, so does the rate of species loss and deforestation. -
ANSWER True
T or F. The more productive forests typically occur on the south-facing slopes compared
to north-facing slopes because of the warmer temperatures and more abundant
sunlight. - ANSWER False
T or F. The forest types is named based upon the species that dominate the overstory. -
ANSWER True
T or F. Water tupelo and bald cypress are two tree spices that can persist within
inundated environments, such as in swamps. Because relatively few species can
tolerate these conditions, these two tree species are usually dominant in many swamp
areas. - ANSWER True
T or F. Currently, capture fisheries have increased in production, whereas production of
fish through aquaculture has stagnated. - ANSWER False
T or F. While threatened and endangered species classification is often more thought of
as applying to wildlife species, it also applies to fishes, invertebrates and plant life. -
ANSWER True
T or F. The majority of wood volume harvested in the US comes from publicly-owned
forests. - ANSWER False
T or F. The proximate cause of decline in grassland birds has been attributed to
pesticides. - ANSWER True
T or F. Because data pertaining to stock populations or harvestable surplus may be
missing, unreliable or otherwise inadequate, sustainable harvest principles would
suggest harvesting below the MSY. This is known as the precautionary principle. -
ANSWER True
T or F. The National Parks Service's mission to manage wildlife populations for the
benefit of human users. - ANSWER False
In addition to human consumption, fish production is used for: - ANSWER Stocking for
recreational purposes and captive breeding of endangered species.
How does the 1973 Endangered Species Act define wildlife? - ANSWER All members of

Yellowstone Park Timberland Reserve
Which term best describes this statement? "The air temperature and snowfall this
winter has been a strong regulator of population abundance and growth of smallmouth
bass in a nearby, shallow lake." - ANSWER Density independence
As forests grow, the trees become larger and the forest density increases, causing
competition and eventual mortality of trees. The onset of competition among trees in a
forest begins at which point? - ANSWER Crown closure
Trends have shown that the number of wildfires that occur annually in the US since 1960
have been: - ANSWER Decreasing
During which period of time did a greater scientific emphasis on wildfire management
begin and expand in the U.S.? - ANSWER 1930-1960
Which represents a biotic component of the walleye fishery in Lake Erie?
a. zooplanton prey
b. The clarity of the water as measured by a secchi disk
c. A charter fishing boat and captain hired by Brutus Buckeye to fish for walleye
d. The temperature of the water in Lake Erie - ANSWER Zooplankton prey
Of all the wildlife species in North America, game species account for approximately
______ percent of all wildlife species. - ANSWER 10%
Using a resource in such a way that the resource is sustainable is a definition of which
approach to management? - ANSWER Conservation
Which of the following is not an example of an activity related to an extractive objective
, of a fishery?
a. Restoration of coastal wetland habitat to provide more nursery grounds for larval
walleye in order to maintain the fishery now and in the future
b. Provide Petco with a supply of clownfish to sell
c. Supply a local restaurant in New Orleans with crayfish for Mardi Gras.
d. Employ the concept of maximum sustainable yield to the New England cod fishery. -
ANSWER Restoration of coastal wetland habitat to provide more nursery grounds for
larval walleye in order to maintain the fishery now and in the future.
What are impacts associated with aquaculture? - ANSWER Nutrient pollution from fish
waste, release of chemicals (e.g. antibiotics) from a fish hatchery into water bodies,
transfer of parasites between hatchery-raised fish and wild populations of fish
Eastern forests are dominated by: - ANSWER deciduous, or hardwood, species
Western forests are dominated by: - ANSWER coniferous, or softwood, species
Which of the following is considered a non-renewable resource?
a. Timber
b. Wildlife
c. Coal - ANSWER Coal
The primary reason that half the wildlife species globally are declining is: - ANSWER
Habitat loss
Managers of the Florida Keys ecosystem have become increasingly concerned with
invasions of the non-native lion fish. They have been continually monitoring and
assessing the abundance and growth rate of the population since its introduction and
have found that currently nothing is regulating the growth of this population. In this
ecosystem, lion fish likely exhibit what type of population growth? - ANSWER
Exponential population growth
Lake Erie fisheries managers have been collecting data on the population dynamics of
the yellow perch for decades. Currently, they have determined that the population
abundance is at its carrying capacity for yellow perch. Based on that information, what
is the relationship between the birth and death rate of yellow perch at carrying
capacity? - ANSWER Birth rate is equal to death rate
Wildlife management that is preventative or protective in order to allow ecological
processes to determine the dynamics of the system is what type of management? -
ANSWER Custodial
Scientists estimate the maximum sustainable yield for the yellow perch fishery in Lake
