1Selected habitats 1: Temperate broadleaf woodland
Most temperate broadleaf woodland is found in the northern hemisphere in:
[blank_start]Europe[blank_end]
[blank_start]Eastern[blank_end] North America
East [blank_start]Asia[blank_end]
- AEurope
- BEastern
- CAsia
- DAfrica
- ESouthern
2Most trees in temperate broadleaf woodlands are [blank_start]deciduous[blank_end] trees that lose their leaves each year. A [blank_start]wide[blank_end] range of tree species live in temperate broadleaf Woodlands.
- Adeciduous
- Bwide
- Csmall
- Devergreen
3Dominant tree species depend upon the soil conditions, for example, the dominant tree species in British broadleaf Woodlands are:
- Abeech
- Bash
- Coak
- Dpalm
- Ebanana
- Fmaple
4Ecological features
-Temperate broadleaf Woodlands do not have a major [blank_start]temperature[blank_end] [blank_start]extremes[blank_end].
-There is no pronounced [blank_start]dry season[blank_end] - water is available all year.
-The soils are usually [blank_start]deep[blank_end] and fertile. The trees play an important role in the soil formation with [blank_start]dead organic matter[blank_end], and its retention by [blank_start]vegetation cover[blank_end] and root [blank_start]binding[blank_end].
-The tree canopy layer is present from spring until [blank_start]autumn[blank_end], so the growth of plants under the canopy is more difficult because they are [blank_start]shaded[blank_end] during the time when the temperatures are best for [blank_start]growth[blank_end]. Many woodland floor plants overcome this by growing early in [blank_start]spring[blank_end] before the trees have produced leaves, for example, British [blank_start]bluebells[blank_end] and snowdrops.
-The lack of available food during the winter causes many animals to become less [blank_start]active[blank_end], store [blank_start]food[blank_end], hibernate, or [blank_start]migrate[blank_end].- Aextremes

6High biodiversity - having a high biodiversity creates a higher [blank_start]ecological[blank_end] [blank_start]stability[blank_end]. No species are completely [blank_start]dominant[blank_end] so a change in the population of one species will have a relatively [blank_start]small[blank_end] impact on the overall [blank_start]community[blank_end] of species.

7Woodland resources - temperate broadleaf woodland was historically important for a wide range of resources.
Wood was used for [blank_start]building[blank_end] construction, fencing, tools, [blank_start]courts[blank_end], wood [blank_start]fuel[blank_end], and [blank_start]charcoal[blank_end] for metal smelting. The Woodlands also provided a [blank_start]food[blank_end] resource for The animals and plants found there, for example, [blank_start]dear[blank_end], fruit, and nuts. Forest resources [blank_start]under longer[blank_end] widely exploited in the UK except timber from commercial [blank_start]plantations[blank_end].- Abuilding

9The hydrological cycle
All [blank_start]trees[blank_end] play a role in the hydrological cycle through [blank_start]interception[blank_end], Evapotranspiration, and the control of water in the [blank_start]soil[blank_end].- Ainterception

11Carbon sequestration
All plants absorb CO2 during [blank_start]photosynthesis[blank_end] but most release it again during [blank_start]respiration[blank_end] and the [blank_start]decay[blank_end] of their vegetation.
Plants with [blank_start]woody[blank_end] tissue can build up a store of carbon in the [blank_start]cellulose[blank_end] and lignin that forms wood, so woodlands are large reservoirs of stored carbon which [blank_start]reduces[blank_end] atmospheric carbon dioxide concentrations.- Aphotosynthesis

12Threats to broadleaf woodland
-woodland [blank_start]clearance[blank_end]
-habitat [blank_start]fragmentation[blank_end]- Aclearance
- Bfragmentation
13Woodland clearance: as societies have developed and populations have grown, natural woodland habitats have been cleared to provide space for new land uses, such as:
- AFarmland
- BPlantations
- CUrban development
- DTransportation infrastructure
- EMineral extraction
- Ffishing
- Gsunbathing
- Hhockey
- Ifootball
14Habitat fragmentation:
Woodland [blank_start]clearance[blank_end] may leave remaining areas that are [blank_start]isolated[blank_end] from each other.
If animals cannot move between these areas, then each separate population becomes more vulnerable to [blank_start]extinction[blank_end]- Aisolated

16Woodland management
Historical methods
-‘Wildwood’: areas with virtually no [blank_start]interference[blank_end], for example, hunting forests.
-Mature [blank_start]standard[blank_end] trees: for example, [blank_start]oak[blank_end] for timber framed houses, furniture, and ships.
-[blank_start]Coppiced[blank_end] woodland: for example, Hazel for fencing.
-[blank_start]Pollarding[blank_end]
These methods often created woodlands with high [blank_start]habitat[blank_end] [blank_start]diversity[blank_end], high [blank_start]biodiversity[blank_end], and high [blank_start]wildlife[blank_end] value.- Ainterference

19Legal protection of ancient woodlands
An ancient woodland in the UK is defined as one that existed before [blank_start]1600[blank_end]. Few Woodlands were [blank_start]deliberately[blank_end] [blank_start]planted[blank_end] before 1600, so a wood that is over 400 years old is likely to have developed [blank_start]naturally[blank_end] a long time ago.
An ancient woodland usually has a very [blank_start]high[blank_end] biodiversity because there has been a long time period for species to [blank_start]colonise[blank_end].
Some species of wild plant colonise woodlands very slowly, so the presence of many such species is evidence that the woodland is ancient. (Eg. [blank_start]Bluebells[blank_end])- A1600
- Bnaturally
- Cdeliberately
- Dplanted
- Ehigh
- Fcolonise
- GBluebells
20Designated protected areas
For example: [blank_start]Sherwood[blank_end] Forest national nature reserve.
In 2012 [blank_start]National[blank_end] [blank_start]Planning[blank_end] [blank_start]Policy[blank_end] [blank_start]Framework[blank_end] states that ‘planning permission should be [blank_start]refused[blank_end] for development resulting in the loss or deterioration of irreplaceable habitats, including ancient woodland and the loss of aged and veteran trees found outside ancient woodland, unless the need for, and benefits of, the development in that location clearly outweigh the loss.’- ASherwood

21Planting of new Woodlands
Large areas of new woodland have been planted in the UK over the past 30 years, usually on small areas of [blank_start]farmland[blank_end]. These have often included a [blank_start]mix[blank_end] of [blank_start]indigenous[blank_end] tree species that are likely to have an increasing wildlife value as the Woodlands [blank_start]mature[blank_end].
They are especially valuable if they join [blank_start]existing[blank_end] areas of woodland, or habitats such as hedgerows, which can act as [blank_start]biological[blank_end] [blank_start]corridors[blank_end], linking small fragmented areas of woodland.- Afarmland

22Selected habitats 2: Tropical Rainforest
Tropical rainforests are the most [blank_start]biodiverse[blank_end] terrestrial ecosystems. They have not been fully researched, but the relative ease with which new [blank_start]species[blank_end] can be [blank_start]discovered[blank_end] suggests that over [blank_start]half[blank_end] of all [blank_start]terrestrial[blank_end] species live in tropical rainforest, although the rainforests only cover about [blank_start]10%[blank_end] of the Earth’s land area.- Abiodiverse
- Bspecies
- Cdiscovered
- Dterrestrial
- Ehalf
- F10%
- G20%
23Ecological features
The tropical climate has been relatively [blank_start]stable[blank_end] over long time periods, compared with regions further away from the equator.This has given rainforest species a long time to [blank_start]evolve[blank_end] and become adapted to local abiotic and biotic factors. This has produced a large number of different species although they are relatively [blank_start]rare[blank_end] and may have small ranges. Being adapted to relatively stable conditions can make species vulnerable to [blank_start]extinction[blank_end] as a small change in environmental conditions may move them outside their range of [blank_start]tolerance[blank_end].- Astable
- Bevolve
- Crare
- Dextinction
- Etolerance
24High light levels allow [blank_start]photosynthesis[blank_end] rates to be high, providing a lot of [blank_start]food[blank_end] energy to support a rich food [blank_start]web[blank_end].
- Aphotosynthesis
- Bfood
- Cweb
25Constant [blank_start]warm[blank_end] temperatures and regular high [blank_start]rainfall[blank_end] allows plants to grow throughout the year without the [blank_start]seasonal[blank_end] changes that occur in higher latitudes. This insures reliable [blank_start]food[blank_end] supplies are available to animals throughout the year. Populations rarely have the seasonal fluctuations found in higher latitudes as there is no need to [blank_start]hibernate[blank_end] or migrate.
- Awarm
- Brainfall
- Cseasonal
- Dfood
- Ehibernate
26Due to [blank_start]stable[blank_end] abiotic conditions, there is little need for most species to [blank_start]evolve[blank_end] to adapt to different abiotic factors. The main [blank_start]survival[blank_end] [blank_start]pressures[blank_end] are produced by abiotic factors such as getting [blank_start]food[blank_end], avoiding [blank_start]predation[blank_end], and [blank_start]involving[blank_end] better interspecies relationships.

27Although there are [blank_start]high[blank_end] light levels, there is also a lot of [blank_start]competition[blank_end] for light. Plants that have evolved to grow a tall [blank_start]trunk[blank_end] will have better access to light but must invest a lot of [blank_start]energy[blank_end] over a long time to produce the [blank_start]wood[blank_end] that forms the trunk.
Smaller plants may need to evolve methods of utilising [blank_start]lower[blank_end] light levels, such as denser [blank_start]chlorophyll[blank_end] or additional [blank_start]pigments[blank_end] to absorb wavelengths of light that passed through the leaves of taller plants. [blank_start]Epiphytes[blank_end] live on higher branches of trees to have greater access to light without being tall. However they may have less reliable water and [blank_start]nutrient[blank_end] supplies.- Ahigh

28With no distinct [blank_start]seasons[blank_end], different plant species do not have to flower or produce [blank_start]seeds[blank_end] and fruit at the same time as each other. So plants have less [blank_start]competition[blank_end] for the services of animals to pollinate [blank_start]flowers[blank_end] or spread seeds. Food in the form of [blank_start]nectar[blank_end], seeds, or fruit is available to animals throughout the year, which increases animal [blank_start]survival[blank_end].

29Most trees are [blank_start]deciduous[blank_end] and shed their leaves every year but different species do so at different times of year. So [blank_start]animals[blank_end] that feed on vegetation do not have long periods where there is no [blank_start]food[blank_end].

31High biodiversity on its own does not make an area important to humans, but it does increase the chances of finding [blank_start]useful[blank_end] species. For example, new [blank_start]food[blank_end] species, [blank_start]medical[blank_end] discoveries, or [blank_start]biomimetic[blank_end] applications.

33Climate maintenance
Tropical rainforests are very important for increasing down wind [blank_start]rainfall[blank_end]. Over half the rainfall in the Amazon rainforest resulted from [blank_start]transpiration[blank_end] elsewhere in the rainforest rather than coming directly from the [blank_start]evaporation[blank_end] of seawater.- Atranspiration
- Bevaporation
- Crainfall
34As with temperate broadleaf woodland and all trees, carbon [blank_start]sequestration[blank_end] by [blank_start]photosynthesis[blank_end] stores large amounts of carbon in tropical rainforest which helps reduce the natural [blank_start]greenhouse[blank_end] effect.

- Asequestration
- Bphotosynthesis
- Cgreenhouse
44Soil maintenance
The warm, moist conditions make dead vegetation [blank_start]decay[blank_end] very rapidly, so nutrients can be [blank_start]reabsorbed[blank_end] by trees very quickly.
Because of this, soils in tropical rainforests are often very [blank_start]shallow[blank_end]. The vegetation cover and tree roots are important in preventing the soil that is present from being [blank_start]eroded[blank_end], as the foliage protects the soil from heavy [blank_start]rain[blank_end] and the [blank_start]roots[blank_end] hold the soil together.Forest [blank_start]clearance[blank_end] can lead to serious soil erosion.- Adecay

46Fuelwood collection
Wood is the most important domestic [blank_start]fuel[blank_end] in rural areas of LEDCs. The rate of the wood collection is usually faster than the rate of [blank_start]re-planting[blank_end] and natural [blank_start]regrowth[blank_end].- Afuel
- Bregrowth

47Timber harvesting
Timber from tropical rainforest is harvested for use in two main ways:
Use in the [blank_start]country of origin[blank_end] for house construction and [blank_start]furniture[blank_end].
Export to [blank_start]MEDCs[blank_end] for use in products such as furniture and doors.- Acountry of origin
- Bfurniture

48Clearance
Subsistence agriculture - sustainable agriculture done by families for [blank_start]personal[blank_end] use. Families create small [blank_start]clearings[blank_end] to farm until the soil nutrients is [blank_start]depleted[blank_end] and the clearing is left to grow [blank_start]wildly[blank_end] again. This has been done for hundreds of years and has cause [blank_start]very few[blank_end] environmental problems.- Apersonal

49Commercial agriculture
As human [blank_start]populations[blank_end] grow, the demand for farmland [blank_start]increases[blank_end] and habitats such as rainforests may be [blank_start]cleared[blank_end]. Rainforest clearance for crops or [blank_start]cattle[blank_end] is often unsustainable, as the poor tropical soils may become [blank_start]infertile[blank_end].If the land is abandoned, it may be difficult for the forest to [blank_start]re-colonise[blank_end] if there is no surviving forest areas nearby.
For example, large areas of rainforest have been cleared for [blank_start]coffee[blank_end] plantations in Vietnam.- Apopulations

50Mineral extraction
there are many valuable deposits of metal minerals present under tropical rainforests, including [blank_start]aluminium[blank_end] and gold.[blank_start]Extraction[blank_end] results in habitat loss and can cause water [blank_start]pollution[blank_end] when the mineral is processed, such as discharges of [blank_start]turbid[blank_end] drainage water, cyanide, and [blank_start]mercury[blank_end].- Aaluminium

51Reservoirs
New [blank_start]hydroelectric[blank_end] power schemes can flood a large areas of forest and create a barrier to mobile species such as migratory fish and river dolphins. The [blank_start]decomposition[blank_end] of dead organic matter in deep, static, reservoir water can produce acidic, [blank_start]deoxygenated[blank_end] water that may be [blank_start]harmful[blank_end] to aquatic life downstream.The flow of water out of the reservoir may be [blank_start]controlled[blank_end] to generate electricity to match demand, but [blank_start]fluctuating[blank_end] river levels downstream can affect wildlife.- Ahydroelectric

52Climate change
[blank_start]Droughts[blank_end] in tropical rainforest caused by climate change will increase the number of forest [blank_start]fires[blank_end] and the area that the fires cover.Fires are also likely to last longer causing more [blank_start]damage[blank_end]. A long fire may [blank_start]boil[blank_end] tree sap and kill the trees.
The populations of many frogs and toads in [blank_start]cloud[blank_end] [blank_start]rainforest[blank_end] are declining, in countries such as Costa Rica. [blank_start]Stop rising[blank_end] temperatures are reducing condensation in clouds are forming higher up the mountains. This reduces the area of habitat that is [blank_start]humid[blank_end] enough for them to survive.
Epiphytic plants such as orchids and air plants absorb water from the bark surface of the trees they live on.
Their populations [blank_start]decline[blank_end] if the air is less humid.
Some computer climate models predict that with some rainforest areas will be replaced by [blank_start]savanna[blank_end] [blank_start]grassland[blank_end].- ADroughts

53Tourism
The expansion of [blank_start]tourism[blank_end] [blank_start]facilities[blank_end] can threaten habitats and wildlife. [blank_start]Ecotourism[blank_end] is an increasingly important way of generating income without having to destroy the forest.
However, in some countries the large numbers of [blank_start]visitors[blank_end] can cause damage, as it has been found in Costa Rica.- Afacilities

55Debt for nature swaps
Many countries that have threatened rainforests are in [blank_start]debt[blank_end] to other countries. The country that lent the money may be prepared to [blank_start]cancel[blank_end] the debt in return for a guarantee that an area of the rainforest will be [blank_start]protected[blank_end].
Conservation [blank_start]charities[blank_end] make negotiate to pay off part of the debt if The country that owes the debt agrees to [blank_start]conserve[blank_end] a wildlife habitat. The [blank_start]WWF[blank_end] has organised debt for nature swaps in this way to protect rainforests in [blank_start]Costa Rica[blank_end] and the Philippines.- Adebt
