Upstream Dimension: Cloud Forests, Protection Basins & Dayan Gunung Hydrology

The upstream territory of North Lombok Regency stretches from the volcanic caldera walls of Mount Rinjani National Park through the dense protection forest ridges of Gangga and Bayan. This highland realm is the island's indispensable ecological fortress, recharging 47 primary springheads that nourish every living community below.

Upstream Biodiversity Catalogue

Endemic Avifauna, Keystone Flora & Protected Wildlife

The montane rainforests of Mount Rinjani harbor irreplaceable Wallacean genetic heritage. The continued presence of apex avian raptors and deep-rooted native tree canopies provides direct proof of catchment stability.

Keystone Endemic Avifauna

Rinjani Scops Owl

Otus jolandae

Status: Near Threatened (IUCN Red List)

Lombok's sole true endemic avian species, scientifically recognized as a distinct taxon in 2013. Functions as an apex nocturnal insectivore controlling forest canopy equilibrium.

Habitat: Primary and mature secondary forest, 25 – 1,350 MASL (Senaru, Torean)
Critically Endangered Apex Raptor

Flores Hawk-Eagle

Nisaetus floris

Status: Critically Endangered (IUCN Red List)

One of the planet's rarest raptors, with fewer than 250 breeding pairs worldwide. North Lombok's montane cliffs serve as a vital nesting haven and foraging corridor.

Habitat: Steep montane ravines and high canopy of northern Rinjani
Signature Watershed Canopy Tree

Klokos Udang

Syzygium formosum

Status: Vital Soil Binder & Hydrological Anchor

Locally christened by indigenous Sasak Dayan Gunung for its exfoliating reddish bark resembling shrimp scales. Its deep, fibrous root matrix anchors steep volcanic slopes against landslides.

Habitat: Submontane rainforest (<1,200 MASL)
Sub-Alpine Flora & Sacred Flora

Mountain Casuarina & Javanese Edelweiss

Casuarina junghuhniana & Anaphalis viscida

Status: Legally Protected Flora

Forms high-altitude windbreak savannas near the caldera rim. Edelweiss (Candar Nyawa) holds deep spiritual sanctity within ancestral Wetu Telu mountain rituals.

Habitat: Sub-alpine volcanic zone (2,000 – 3,726 MASL)
Arboreal Primate & Herbivore

Ebony Leaf Monkey & Javan Rusa

Trachypithecus auratus & Rusa timorensis

Status: Vulnerable (IUCN Red List)

Inhabiting the dense canopies flanking protected springheads. Instrumental in native seed dispersal, ensuring perpetual natural forest regeneration across watersheds.

Habitat: Deep forest valleys of Santong and Menanga Baris
Wild Forest Epiphyte

Rinjani Wild Orchid

Vanda limbata

Status: CITES Appendix II Protected Epiphyte

Native Lesser Sundas orchid known for its ornate, resilient blossoms. Highly vulnerable to illicit poaching and habitat degradation in buffer zones.

Habitat: Epiphytic on ancient host canopy trees
Empirical Vulnerability Audit

Ecological Pressures, Policy Deficits & Governance Dilemmas

Despite statutory protection zones, the upstream landscape experiences acute structural friction that directly jeopardizes island water sovereignty and highland farmer livelihoods.

Law Enforcement & Governance Deficits

Illegal Timber Extraction & Sonokeling Poaching

Protected forest slopes across Santong, Gangga, and Bayan face persistent incursions by illegal logging syndicates targeting high-value Rosewood (Dalbergia latifolia) and Klokos Udang. KLHK Law Enforcement (Gakkum) reports reveal covert nocturnal extraction through rugged trail networks, causing canopy degradation and accelerated soil erosion.

Ground Consequence: Accelerated siltation across downstream communal weir intakes and reduced aquifer recharge.
Climate & Ecological Vulnerability

Wildfire Vulnerability Across High-Altitude Savannas

Protracted dry seasons aggravated by El Niño anomalies leave the dry tussock grass savannas along the Torean and Senaru ascent routes exceptionally prone to wildfires. Recurring burns disrupt natural seedling regeneration of Casuarina stands and shrink the nesting habitat of the endemic Rinjani Scops Owl.

Ground Consequence: Depletion of topsoil vegetative anchors, triggering catastrophic mudflows upon sudden tropical downpours.
Policy & Customary Land Rights

Tenurial Ambiguity: State Forest Boundaries vs Ancestral Domains

Historical top-down state forest gazettement frequently overlapped with customary ancestral domains (Tanak Paer) of the Sasak Dayan Gunung communities. The absence of participatory boundary delineations creates administrative friction between forestry patrols and indigenous agroforesters cultivating heritage crops.

Ground Consequence: Legal insecurity for indigenous agroforestry systems cultivating heritage coffee, candlenut, and sugar palm.
Hydrological Crisis

Degradation of 47 Vital Springhead Catchments

Canopy conversion on steep upper gradients into seasonal monocropping without bench terracing causes discharge volatility across 47 primary springheads. Lifeline springs including Tibu Genting, Gangga, and Lokok Kerewek experience severe volume swings between wet and dry cycles.

Ground Consequence: Acute clean water shortages for municipal distribution (PDAM) and drought across thousands of downstream rice terraces.
Statutory Law & Customary Jurisprudence

Governance Architecture, Indigenous Recognition & Awig-Awig

Upstream conservation across North Lombok synergizes constitutional statutory law with centuries-old customary legal councils upheld by the Krama Adat Dayan Gunung federation.

Recognition & Protection of Customary Law Communities (MHA)

North Lombok Regency Regulation (Perda) No. 2 / 2020

Formally acknowledges the sovereign rights of indigenous communities (including Bayan and Bentek) to govern and safeguard customary forests (Gawah Adat) under traditional customary tenure.

Spatial Plan: Strict Ecological Protection & Water Recharge Zones

Spatial Planning By-Law (Perda RTRW KLU No. 9/2011 & 2021–2041 Revision)

Designates over 13,900 Ha of protection forests as absolute conservation zones where non-forestry commercial conversion and disruptive land clearing are strictly prohibited.

Decree of the Minister of Environment and Forestry (SK MenLHK)

Establishes definitive statutory zoning for Mount Rinjani National Park Section I North Lombok (12,031.30 Ha) as a national ecological sanctuary.
