A wildlife reserve (sometimes called game reserve, game park or wildlife preserve) is an area of land where different kinds of wild animals are kept and protected in order to avoid their extinction; while also aiming to generate income from them.
Generally, wildlife reserves may be governmental or privately owned. Examples of animals preserved as wildlife include gorillas, monkeys, snakes, tigers, lions, giraffes, hyenas and crocodiles.
Please read on agricultural land and its uses here.
The presence of wildlife reserve in a nation will provide 2 important benefits. These are:
Source of foreign exchange.
Development of the country's economy through tourism.
Note: The indiscriminate killings of animals are forbidden in a wildlife reserve center.
Please read on the roles of government in agriculture here.
The image above shows the various national parks (forest and wildlife reserves) in Nigeria.
You can read on forest reserves in Nigeria and importance of forests here.
Below are some major wildlife reserves or game reserves in Nigeria:
Yankari Game Reserve in Bauchi State.
Gashaka Gumti National Park in Taraba State.
Kainji Lake National Park in Kwara State.
Borgu Game Reserve in Kwara State.

Amazing facts in Agricultural Science
Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum
Peanuts are legumes and not nuts
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments
Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them
Cows have got the ability to walk up stairs, but not down stairs
A group of cows is called a team, drove or herd.
People just prefer to call them herd
NOTABLE POINTS IN Agricultural Science
Below are the classification of crops based on their uses:
Oil crops
Vegetable crops
Latex crops
Drug and Medicinal crops
Beverage crops
Fibre crops
Fruit crops
Root and Tubers
Legumes
Spices
Cereals
All crops are plants but not all plants are crops. Below are some instances:
Weeds are considered as plants, not crops.
Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.
Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
Meanwhile, always understand that all crops are plants, and they are grown for food, money or something beneficial.
Below are some of the problems of agriculture in Nigeria:
Lack of mechanized farming
Poor government policies
High cost of fertilizers
Lack of education
Lack of storage facilities
Bad road network
Poor research facilities
Please read a detailed explanation on the problems of agriculture in Nigeria here.
Secateurs are agricultural tools.
Secateurs are also referred to as pruning shears or hand pruners.
It looks like a pair of scissors.
It’s used for trimming flowers and leaves.
It is also used for pruning the branches of shrubs.
An example of an agricultural tool is the hoe. It is shown below:
We have a variety of hoes.
They are generally used for tilling the soil.
They are used for making trenches in farmlands.
A hoe is utilized in harvesting crops like yam and cocoyam
They are also used for cutting weeds on farmlands.
