Biodiversity

Foreign trees often have difficulties adjusting to their new environment. The Eucalyptus is growing apparently without trouble, but it is not capable of sexually reproducing itself, i.e. the seeds do not germinate in the Ethiopian soils. Therefore, the standard procedure of introduction is the planting of seedlings. The young trees soon start to compete very efficiently with other vegetation. It is a fast grower, quickly reaching above other trees and suppressing them. At the same time, a chemical component in the leaves and roots prevents the growth of other trees and herbs. This leads to a monoculture with Eucalyptus as the only tree species and eventually no ground cover.

The Eucalyptus: Tactical Toxicity

A chemical component with an intricate competition-oriented toxic defence system in the leaves and roots of Eucalyptus trees counteract the growth of other trees and herbs. This chemical component leads to wildlife starvation, a water shortage, and a monoculture with Eucalyptus as the only tree species and eventually no ground cover. This chemical component causes severe erosion, which is easily observed in the water running through Addis Ababa during the rainy seasons. Due to these shortcomings in the water-preserving capacity of the Eucalyptus plantation, it cannot counterbalance the uneven distribution of rain. The result is often torrential flooding and severe erosion in the down-slope areas.

The Ancient Creation Of The Ground's Biodiversity

With the Important Legacy of Native Trees

The Foundation of Natur's Symbiosis.

The symbiotic synergy within the biodiversity of the native
plants' roots thereby counteracted the water resistance of
the dense-packed ground and opened the soil's ability to
stabilize porous permeability. This basic phenomenon
between plants and soils allowed the water to pass
through deeper soil layers and to reach aquifers.
The Complex Sciences of Nature

Thanks to complex symbiotic biodiversity development in a remote geological time of the evolution of plants and ground-living organisms, they obtained the symbiosis to open the Earth's surface layers' permeability. Thus, these ancient organisms with the native original plants liberated the otherwise water-repellent surface of the soil and gave the ground its water-absorbing properties. Hence, the indigenous forest elucidates as the main factor for its ability to saturate the aquifers, with the potent water accumulation effect within the actual depth of the mountain massif's total configuration.

The Armoured Biodiversity from the Past

With the intricate heritage from guardian biology from the primaeval forest's armoured and water-assisting lushness, the native roots and microorganisms in symbiosis interfered by preventing starvation caused by the otherwise threatening brittle and fragile soils. Hence, with their intricately stabilizing fibrous roots, these plants in ancient times made a symbiosis with the surrounding Earth's organisms and initiated at the beginning of time the path for the water through the soil and towards the Earth's groundwater reservoirs.

The Vegetation, Geology and Their Unique Soils

These phenomena are interconnected, and the indigenous vegetation and biological micro-structure are crucial for distributing rainwater to the aquifers and preventing erosion. Prehistorically, in Ethiopia, geology, water, plants, and soil fulfilled in antiquity still retain their natural properties to withhold much water and nourishment within its landscape's mountain massif and deeper soils. The body naturally harboured water, maintained in the mountains' native highland vegetation, primaeval forest, and aquifers, can be considered and scientifically analysed with considerable help from the methods used for highly complex dam and reservoir constructions.

Biodiversity with Geology and Water Creation

Natural forest areas with native undergrowth are crucial for conserving species richness in animals and plants. This wild forest and scrub are also essential for creating groundwater within the geology of the natural mountain reservoirs in the underground aquifers. Naturally, a priority should prevail for the natural forest, especially on the mountain massifs. However, observing high alerts on foreign and invasive species and their incompatible heritage is crucial.

The Legacy of Vegetation and Their Ground

Crucial here prevail the underground and geological compounds that slowly filter this water and transform it into more permanent and long-lasting groundwater in the more deep-lying aquifers of the rock massif. These considerations of the native Nature appear in a complex and beautiful picture of lifeforms where they optimized their genetic code through the aeons.

The Importance of Geology for Ecology

The Eucalyptus Tree

An Intruder from a Time of Imprudence for Nature

The Eucalyptus Tree: A Rejection of Precious Water

The Eucalyptus demands large quantities of water, regrettably due to its destructive ability to reject deluges into torrential flash floods. Areas that were periodically wet and had flora adjusted to such conditions were drained by planted Eucalyptus. Because of the poor flora and the lack of plants needed by specialized insects and birds, the biodiversity of a eucalyptus plantation is extremely low. Also, when timber is continuously removed from the area without any fertilizer input, the soil quality gradually decreases, reducing the possibility of reintroducing indigenous species.

The Devastating Threat from a Foreign Toxicity

Therefore, it is crucial to prioritize scientific research and practical measures to combat erosion because torrential floods caused by erosive forces can be a significant threat. The harmful impact of foreign trees on Ethiopia's natural environment, such as the toxicity of artificially implanted Australian eucalyptus trees, highlights the need for careful investigation into the detrimental effects of incompatible substances and organisms that lead to soil degradation and erosion. Therefore, understanding natural sciences is crucial before introducing foreign species into a potentially vulnerable habitat.

The Ecological Background of the Native Forest

Direction Map to the Alluring Past
The Native Trees and Their Capacity to Distribute Purified Groundwater.
Thanks to the evolutionary optimization of the ancient native trees' ecology, they genetically evolved into formidable distributors of superficial rainwater to the aquifers, allowing this water to penetrate the soil's otherwise porous resistive structure. Thus, the native, ancient plants loosened up the soil's otherwise dense fabrics through these intricate fibrous networks of plant roots.

The Original Properties of Trees & Soils.

The Earth's surface layer's permeability resistance opened its porous permeability and allowed water to pass to the deeper regions of the soil layers and aquifers. Hence, the intricate biology within the ancient life forms optimized their DNA to distribute this water into the deeper layers of natural mountain areas. These native trees gave the ground with its soils and deeper rocks a significantly increased and specified deposit in quantity and quality of purified water.

The Wild and Fertile Forest from the Ancient Era

This original forest (40) just to the right of point (16) is captivatingly wild and consists of more than 50-year-old indigenous Juniperus procera trees. This native woodland (40) provides a unique contact with Nature with somewhat exotic primaeval lushness and a great surprise. This native Juniper woodland (40) is massive in appearance and stunning in vitality, with a perfect, lush and dense undergrowth. This native forest's vibrancy and lushness are beyond what a visitor would usually expect in proximity to the Capital.

The healing capacity of a native forest

The natural health and fertile beauty in this Indigenous Juniper forest (40) illuminates with precision the healing ability of a native forest and the severe Nature and habitat destruction that occurred at the introduction of the Eucalyptus tree. The importance of careful research regarding knowledge in natural sciences is given a rigorous and evident example before any foreign species is regarded as possible for an introduction into an unfamiliar and vulnerable habitat.

However, much work has been done to re-form an upper soil layer with a protective undergrowth. It would, therefore, be very pleasing to gain information about a new generation of this highly blessed historic tree, which still grows in the magical, graceful and appealing landscape of Entoto Natural Park.

Environment and Prosperity.
The indigenous Podocarpus falcatus (P. gracilior) tree is scarce at Entoto with a few mature trees and does not appear to produce seedlings with the Eucalyptus planted surroundings. It seems that it is no longer possible to give surviving progeny in the barren, eroded, exposed lands that have been formed since the introduction of the alien eucalyptus tree over a hundred years ago.

The Original Nature for Water Health -

Indigenous Variation of Habitat Creation

Indigenous Trees
When designing with Nature, due care prevails in creating habitats (biotopes) suitable for the area's physical conditions is essential. Juniperus procera is the natural species of Entoto, and it should dominate the future Natural Park. However, to preserve the natural health with the diversity of plants, a specific variation in species prevails as outermost crucial to the Park's restoration, thus requiring a wide variety of species within the indigenous forest.

Entoto Natural Park's Natural Habitat
The 17km² of the Park's mountainous terrain provides excellent variations in topography, humidity, climate, and soil. Given due care for the unique conditions specified for each spot when planting and managing, these considerations are crucial for the indigenous vegetation's health. These analyses of topography's essential impact on the ground's and plant's stability and health constitute the primary source when estimating the restoration of the Park's ground and natural habitat. (Håkan Blanck and Pia Englund, Entoto Natural Park 1995).

Entoto's High Plateau and its Amazing Nature

Image: Juniperus procera trees,

Bees' Cliff, the High Plateau.

Juniperus procera Tree
Ecology: A valuable timber tree indigenous to Ethiopia and eastern Africa highland forests 1,500-3,000 m. It is the largest Juniper in the world. It does best in high rainfall but can survive dry once established. It performs well in Moist and Wet Weyna Dega and Dega agroclimatic zones (Azene Bekele-Tesemma 1993).

Incredible Wildlife Views with Meandering Streams
This plateau just above Bees' Cliff is a magnificent place with a great panorama view over the stream and many characters in the landscape. When the scene turns south, the abyss Bees' Cliff (14), the ravine, is very close, where the river's further gorge meandering (35) becomes intuitively felt through the profound cooling airflow rising from the unknown abyss below the field of view.

A Time of Fragrance, Harmony and Beauty.

At the end of the rainy season in September - October, the high plateau becomes a deep attraction where streams and waterfalls stabilize. A gentle, romantic flow of ideal conditions becomes evident in October- November. A purging fresh stream runs by leaps and joy beyond the secret path of Kidane Mehret's sacred stone walls. Beauty shines beyond hidden depths and abyss to be seen at the Bees' Cliff (14). These photos of water-filled streams and cascading waterfalls are shot just above Bees' Cliff (14) at Entoto's southern highland plateau - from early October to the beginning of November. All of these active water sports photographs passed about one to two months since the long rainy season ended.

The Importance of Indigenous Ethiopian Trees

Podocarpus falcatus (P. gracilior)

This tree is scarce at Entoto and does not appear to compete with the Eucalyptus planted surroundings. It seems that it is no longer possible to give surviving progeny in the barren, eroded, exposed lands that have been formed since the introduction of the alien eucalyptus tree over a hundred years ago. However, much work has been done to re-form an upper soil layer with a protective undergrowth. It would be a very significant surprise to receive information about a new and naturally germinated generation of this highly blessed historic tree, which still grows in a magical, graceful, and appealing landscape.

The Endemic Restoration

Environmental restoration requires scientific research, time, and labour. It also demands massive protection projects to offer young plants a replacement for the lost biotope and its vital natural protective properties. Hence, restoring a lost biotope is complicated and requires much work to recreate a reliable substitute for the missing shielding armour of the primaeval forest. Therefore, due to the absence of the essential protective functions of mother trees and other plants, enormous efforts are required to recreate these guardian functions to shield the tender indigenous seedlings.

CAUTION: The Native Shielding Undergrowth

An unprecedented vulnerability arises because the two related species have the same peculiarity in lifting their seeds from the ground to the height of their crisp stalk. This species makes this seed presented with utmost sensibility and thus becomes an immediate victim on a hard and away offensive clay-soil crust or herbivorous. This vulnerability with an exposed uplifted grain applies to the Podocarpus tree, elucidating the importance of shielding undergrowth.

This peculiarity in seed design of setting kernels to sprout with the high lift was developed at the beginning of these trees' era (evolution) and in epochs long before any human culture or species. Through this evolutionary prehistory, these seed stalks and kernels were naturally received with a moist, typically loose and absorbing soil (humus) and a surrounding of dense protective undergrowth that could hide and shield these so tender exposed vertically raised kernel stalks.

An evolutionary legacy from a time of natural wealth

Podocarpus falcatus

A beautiful memory that attracts modern science and art.

With glowing passion and warmth, it is still spoken among the residents of Entoto about when the water level a reasonable time after the rainy season still stood one metre higher in Entoto's deep streams and enchanting nature rock baths. It is thus quite close to the time when Entoto's mountain massif and its canyons could carry significantly higher water quantity and, therefore, supply the population in the Capital with fresh water to a much greater extent.

Conclusion and Wonderful Solution
This small Podocarpus tree carries a unique heritage that can be very important for the Park's legacy. This tree's seed was picked from the mother tree in the circle (B), west of the path, left of the area (39) and clearly above (38). The stalk to the seed of this tree is considerably more significant in height than the equivalent of the Juniper tree seed. With this uniqueness of raising their brittle stems, an excellent and traditional solution arises where Rosa abyssinica guards the seedlings thanks to the sharpness of its defending thorns.

Biodiversity: DNA Selection for a Site
(Oxford Academic)

Choosing the Right Mother Tree for Seed

The distant location but within the same country, developed fauna and flora have undergone an extremely long evolutionary optimization to best adapt to the unique condition of its geological and surrounding genetic characteristics. The unique habitat in a particular region within a country imprinted the native indigenous to receive their distinctive property of plant and wildlife depending on the remoteness of the unique climate.

The Importance of Seed's Evolutionary Heritage

Hence, due to this isolated location on a country's mountainside or within its secluded gorge, the endemic tree created the specificity of their genetic heritage and the soil's uniqueness. Therefore, the trees' genetic background and evolutionary connection to a country's landscape make a precious legacy for their seeds, which inherit well-adapted genetic characteristics to the location's biological uniqueness.

Assessing Seeds Based on the Climate Zones of the Country

Hence, the genetic legacy's impact in Ethiopia's various climates and altitudes creates trees that, although belonging to the same species, developed a difference in genetic heritage to deal with these different climate zones. Therefore, it's crucial to consider the uniqueness of DNA when selecting the appropriate seed for a particular location. Thus, the mistake of using the seed from a tree with its genetic origin from a moist and shady gorge as seedlings on a dry southern slope undermines these trees' ability to survive and other organisms, including humans.
