What animals eat marram grass?
Sometimes humans kill marram grass by driving or walking on it too much and never giving it a chance to grow. Rabbits and sheep may also eat it up. You can see where this happens because the grass has gone and there are patches or paths of bare sand. When this happens the dunes may blow away.
How long does marram grass survive?
This plant is highly adaptive in sand, and can withstand burial for more than one year.
What is the function of marram grass?
The dense, spiky tufts of Marram grass are a familiar sight on our windswept coasts. In fact, its matted roots help to stabilise sand dunes, allowing them to grow up and become colonised by other species.
How deep are marram grass roots?
Marram Grass Factfile Marram roots can grow up to 7cm in 10 days. Marram can survive when buried by 1 metre of sand/year.
How does marram grass reduce water loss?
Marram grass has a rolled leaf that creates a localized environment of water vapour concentration within the leaf, and helps to prevent water loss. This slowing of air movement once again reduces the amount of water vapour being lost. A waxy cuticle on the leaf surface also prevents evaporation.
Is marram grass native to Australia?
Marram grass, that dry, spindly grass scattered across most Australian coastal sand dunes, isn’t native to Australia. It was introduced to Australia from Europe in the late 1800’s with a very specific purpose: to help stabilise coastal dunes. The reason Marram is used is because it’s very good at what it does.
How does marram grass survive?
Like other xerophytes, marram grass is well adapted to its surroundings in order to thrive in an otherwise harsh environment. Marram grass has a rolled leaf that creates a localized environment of water vapour concentration within the leaf, and helps to prevent water loss.
How does marram grass survive in sand dunes?
Surviving happily on free-draining sand on windy coasts, the plant does everything it can to prevent unnecessary water loss. The waxy leaves are rolled inwards to prevent evaporation from the surface, while tiny hairs alongside the inside minimise air flow that could carry water away.
Why does marram grass reduce water loss?
What adaptations does marram grass have?
Marram grass grows on sand dunes. Its leaves have adaptations to reduce transpiration in dry, windy conditions….Leaf adaptations.
| Adaptation | Explanation |
|---|---|
| Rolled leaves, leaf hairs, and stomata sunk in pits | Traps moist air, which increases the humidity and reduces the diffusion of water vapour |
Why does Marram grass have long roots?
Metres-long roots reach down in search of moisture, while creeping stems called rhizomes extend widthways below the surface, sending down even more ladder-like rooting structures along their length.
Does Marram grass grow soil?
This native grass is frequently found around the UK’s coasts and beaches, especially in the south and west. As a coastal plant, it is very tolerant of salt and sea spray, and grows in sand or very free-draining soil. …
What kind of animals live in marram grass?

Why is marram grass important to the environment?
Marram grass was once harvested and weaved into mats for barn roofs, nets for fishing and even shoes. Traditionally, each family had its own sand dune, but the whole village would often be involved in collecting the grass. Today, the importance of Marram Grass in stabilising these fragile habitats has curbed its harvesting.
What do the leaves on marram grass look like?
The dense tufts of spiky Marram grass are a distinctive feature of this plant. Its leaves are rolled and it displays densely packed, golden flower spikes. Widespread around the UK’s coast. Did you know? Marram grass was once harvested and weaved into mats for barn roofs, nets for fishing and even shoes.
