Grassland Ecosystem Adaptations and Conservation

The video explores the unique biodiversity of native grasslands on Viv's property, highlighting the diverse plant and animal species that inhabit these ecosystems. It discusses the importance of pollinators, the role of soil organisms, and the threats posed by pests like foxes and feral cats. The video also emphasizes the conservation efforts and management practices needed to protect these vital ecosystems, including careful grazing management to maintain biodiversity and prevent soil erosion.

What makes the native grasslands appear special despite looking like a regular paddock?

• Presence of large trees

• Lack of any visible life

• Diversity of native plants and animals

• Presence of cows and sheep

How do grassland plants primarily reproduce?

• Through close relationships with insects

• By water dispersal

• Through wind pollination

• By self-pollination

What is a significant threat to native animals in grasslands?

• Lack of food

• Excessive rainfall

• Predation by foxes and feral cats

• Overpopulation

What role do ants play in the grassland ecosystem?

• They destroy plant roots

• They are the main pollinators

• They act as excavators and provide food for other animals

• They are primary predators

Which of the following is a unique adaptation of the native pea Swainsona?

• It can survive without water for months

• It has deep roots for water storage

• It uses twisting petals to clasp pollinators

• It grows only in shaded areas

How do grasslands help in preventing soil erosion?

• By growing tall trees

• By creating barriers with fallen leaves

• Through strong fibrous roots holding the soil

• By absorbing all the water

What is one of the main benefits of grasslands to the broader landscape?

• They increase the temperature

• They store carbon and provide oxygen

• They reduce biodiversity

• They cause soil degradation

What is a key conservation strategy used by Viv and her husband?

• Allowing unrestricted animal access

• Planting non-native species

• Careful management of grazing

• Complete isolation of grasslands

Why is it important to maintain insect diversity in grasslands?

• To increase soil acidity

• To provide food for native animals

• To reduce plant growth

• To attract more predators

What is the main goal of Viv and her husband regarding their grassland property?

• To convert it into a pasture

• To use it for industrial purposes

• To protect and conserve the native ecosystem

• To build a residential area
