Hizbullah Nature Reserves
Hezbollah Nature Reserves were a system of Hezbollah strongholds built in Southern Lebanon between the Israeli withdrawal from Lebanon 2000 and the 2006 Lebanon war. The term "Nature Reserve" (Hebrew: שמורת טבע, shmorat tev’a) was originally IDF slang and refer to the fact that they were primarily placed in the countryside away from habitation and were declared off-limits to the IDF during the war, due to fear of high casualties.
Human Rights Watch wrote in an extensive report published about a year after the war that "we found strong evidence that Hezbollah stored most of its rockets in bunkers and weapon storage facilities located in uninhabited fields and valleys,… and that Hezbollah fired the vast majority of its rockets from pre-prepared positions outside villages."
An Israeli elite unit stumbled into a Nature Reserve near Maroun ar-Ras and suffered heavy casualties. "We didn’t know what hit us," said one of the Maglan soldiers. "In seconds we had two dead." "We expected a tent and three Kalashnikovs — that was the intelligence we were given. Instead, we found a hydraulic steel door leading to a well-equipped network of tunnels." The Maglan troops then rallied and killed 5 Hezbollah fighters.
After the battle of Maroun ar-Ras, the head of IDF Northern Command Maj.-Gen. Udi Adam forbade any further attacks on Nature Reserves. "A nature reserve can swallow an entire battalion," he said. According to Haaretz "[t]hroughout the war the General Staff and the Northern Command restricted offensive operations into these areas, following the initial encounter…[at] the "nature reserve" code-named Shaked near the town of Maroun al-Ras."  The well entrenched Nature Reserves were not vulnerable to artillery or air bombardment. The decision not to attack these positions, sometimes only hundreds of meters from the Israeli border, made it possible for Hezbollah to continue firing rockets over Northern Israel throughout the war. Most of the short range Katyusha rockets fired on Israel during the war were fired from Nature Reserves.
In December 2007 the Knesset Foreign Affairs Committee issued the findings of its investigation into the 2006 war in Lebanon. It condemned the senior IDF command in unusually severe terms and said that the army's methods of fighting "played into Hezbollah's hands." It was especially critical of the delay in launching a ground war and refraining from attacking the Nature Reserves.
Another Nature Reserve was found at Labbouna, on a forested hillside a few hundred meters from the Israeli border and some kilometer from the UNIFIL headquarters at Naqoura. The area was sealed off by Hezbollah in 2002 and declared a "military zone". Neither Israel nor UNIFIL understood what Hezbollah was up to until the 2006 war. "We never saw them build anything," a UNIFIL officer told Nicholas Blanford. "They must have brought the cement in by the spoonful." Hezbollah maintained a clearly visible outpost nearby that was immediately shelled by the IDF on July 12, after the abduction of the two Israeli soldiers. This outpost however was only a decoy that was already abandoned and the fighters had relocated to the covered positions in the Nature Reserve.
The Hezbollah positions had a commanding view of northern Israel all the way to Acre and Haifa. From the first day of the war this Nature reserve was a source of almost constant Katyusha rocket fire. Israel repeatedly tried to knock out the launch site by massive artillery shelling and air strikes, including the use of cluster bombs and phosphorus grenades. But the rockets continued to be fired until the last hour before the ceasefire.
Hezbollah fighters completely commanded the terrain to the south and claimed to have destroyed an armored bulldozer and a tank only 6 meters into Lebanese territory, on Aug 8, 2006. The IDF confirmed that Capt.(res.) Gilad Balhasan, 28, of Karmiel, and St.-Sgt.(res.) Yesamu Yalau, 26, of Or Yehuda were killed in the incident.
The IDF however bypassed Labbouna and had it effectively surrounded for most of the war but there are no reports of any Israeli attempt to capture the area. Hezbollah fighters who were stationed at Labbouna during the war claim to have launched a raid on an IDF position inside Israeli territory, killing and injuring several Israeli soldiers, including an officer. IDF confirmed that an officer, Maj.(res.) Nimrod Hillel, wase killed in the area of Labbouna on August 10. According to Hezbollah all of the resistance fighters at Labbouna survived the war but several fighters reported spitting blood and experiencing prolonged health effects after inhaling white phosphorus gases.
After the ceasefire Hezbollah withdrew from the area in accordance with UN resolution 1701. The IDF then entered the area and dynamited the large bunker system before withdrawing from Lebanon. Towards the end of the war the IDF "chanced" upon an until then unknown well-equipped bunker overlooking the road where the abduction of the two soldiers took place.
Nicholas Blanford visited an untouched and apparently abandoned Nature Reserve near Rashaf more than six months after the war. The area is about six kilometers from the Israeli border and saw heavy fighting in the last days of the war. The large deserted bunker was accessed through a narrow 6 meter shaft that led into a 60 meters long main passage, with steel doors every 10 meters. Blanford estimated that the main section was 35–50 meters under the surface. The facility was fitted with drainage, air ventilation and electricity as well as a bathroom and a kitchen. It had multiple entrances and exits. 
After the war UNIFIL searched southern Lebanon and found 33 Nature Reserves scattered across the countryside.
In January 2007 IDF found two bunkers, connected by a tunnel, on Israeli territory along the Lebanese border. The bunkers contained food and equipment and were dynamited by the IDF.
