Ngokwe- IZiko leMithombo yeHlathi laseOregon (OFRI) , ukusika okucacileyo yinkqubo ethi yonke imithi ekwicandelo elinikiweyo lehlathi igawulwe ngaxeshanye, kushiyeke inani elincinci kuphela lemithi limi. Ngelixa i-OFRI ibonisa ukuba imithi ekuthethwa ngayo iphinda ityalwe emva kweminyaka emibini, ukutyala kwakhona akuwulungisi wonke umonakalo onokubangelwa kukucoca.
Ukuphulukana nendawo yokuhlala
Imithi esuswe ngexesha lokucoca ibiyinxalenye yendalo yendawo. Ngokwe-OFRI, ezinye izilwanyana ezixhomekeke emithini zinokufuduswa ngenxa yokusikwa, kwaye banokufumana indawo ezintsha zokuhlala. Iintyatyambo zalapha ekhaya zisenokusilela ukuziqhelanisa. Inkqubo ye- INgxowa-mali yeWorld Wildlife (WWF) ithi uninzi lwezilwanyana ezikule meko azizukuziqhelanisa neendawo ezintsha zokuhlala, kwaye ziya kuba sesichengeni sokuhlaselwa ngamarhamncwa.
Amanqaku afanelekileyo- Iindleko zeefowuni zesikolo esikolweni
- Ukutshatyalaliswa kwamahlathi eUnited States
- Iikati ezi-5 zokulunywa ziimpawu zosulelo akufuneki uzihoye
Iziphumo zeNdawo yeNdalo
Ukucoca ukusika kunokuba neziphumo ezinzima kubume bendalo, nangona kunjalo. Ngokwe- Isebe lezamahlathi lombutho wezokutya nezolimo wezizwe ezimanyeneyo (FOA) , iinkqubo ezilula zorhwebo ezichaphazelekayoukusetyenziswa kwehlathiinokushiya indalo eyahlukeneyo isesichengeni sezityalo nezilwanyana.
Isongelo seentlobo ezihlaselayo
I-FOA ibhekisa kwiimeko ezithile apho iintlobo zezityalo ezingenelelayo zithathe indawo yeentlobo zembovane zemveli njengesiphumo esingathanga ngqo seenkqubo zokucoca. Ukuphulukana nokuba zimbalwa iintlobo zemveli kunokutshintsha yonke intsalela yendalo. Ingathatha iminyaka ngaphambi kokuba i-ecosystem ekuthethwa ngayo ifumane into eqhelekileyo.
Iingxaki ngeeNdidi eziNgenayo
Inkqubo ye- UMbutho weSizwe weZilwanyana zasendle (NWF) icacisa uninzi lweengxaki ezithile ezinokubangelwa zizilwanyana ezingenelelayo. Utshintsho kwikhemistri yomhlaba lunxulunyaniswe neentlobo ezingenelelayo ngokwe-NWF, ke izityalo ezifunwa ngabantu kunye nezilwanyana zasendle zengingqi zinokuchaphazeleka ngokungangqalanga zizilwanyana ezingenelelayo. I-NWF ikwachaza ukuba iintlobo zezinto ezingenayo zinokugcwalisa iiches ngaphambili ezazifudula zihlala izilwanyana ezazibalulekile kuqoqosho ebantwini okanye zibalulekile kwisondlo kubomi bezilwanyana zasendle ngelixa zona zinokungancedi. Iintlobo ezihlaselayo zingazisa izifo ezitsha, ezinokuthi zichaphazele abantu kunye nezilwanyana zasendle, ngokwe-NWF.
Amanqanaba e-Carbon dioksayidi
Njengoko i-Keisha Raines e-Gcina iSierra ibonisa, phantse nantoni na esusa inani elikhulu lemithi iya kuba nefuthe kumanqanaba e-carbon dioxide kuba imithi isebenza njenge-carbon sinks esebenzayo. Ukucinywa kwesikali esikhulu kunokuba nefuthe elibonakalayo kutshintsho lwemozulu.
Ukhukuliseko lomhlaba kunye nomonakalo womhlaba
Ngokwe-WWF, imithi ingasebenza njengeeankile zomhlaba. Ukususa ezo ankile kunokwenza umhlaba ube sengozini ngakumbi kukhukuliseko. Imvula ikwabonisa ukuba ukususwa kwemithi ngexesha lokucoca kungasusa ibhaktiriya, iintshulube kunye nefungi egcina nokunyanga umhlaba wehlathi, kunye nokususa ezi zinto ziphilayo kungabeka ezinye izityalo zehlathi emngciphekweni wokugula. Inkqubo ye-ukuthotywa komhlabayenye yezona ngxaki zinzima zokusingqongileyo ezijamelene noluntu ngoku kwaye ukucoca iindlela zokucoca kuphela kunegalelo kuko.
Umngcipheko weNtlekele yendalo
- Imvula ibonisa ukuba ukucoca ngendlela ecocekileyo kungazenza mandundu iziphumo zemithi ngenxa yokuba imithi elahlekileyo ingasakwazi ukusebenza njengezithintelo kunye nezika amanzi agqithisileyo.
- UDaniel Rogge kwiYunivesithi yaseWisconsin u-Eau Claire uxoxa ngento yokuba ukucoca kunganyusa umngcipheko wokuwa komhlaba. I-Rogge ibonisa ukuba iingcambu zinceda ukubambelela emhlabeni kwaye isigqubuthelo sehlathi sinceda ukugcina ihlathi lome noko xa kugawulwa oomatshini ngokwawo kunokuwudodobalisa umhlaba ongaphezulu kwaye kuwenze ungabinamanzi.
- I-FOA ixoxa ngeendlela apho ukucoca kunokutshintsha ukuxhaphaka kwezifo ezahlukeneyo kwiindawo ezahlukeneyo. Umzekelo, ukucoca kungadala indawo entsha yokuzala iingcongconi, ezinokudlulisela izifo ezibulalayo ukusuka kumalariya ukuya kwi-yellow fever. Ukuqhuma kwesifo seLyme eUnited States nako kulandelwaukuthotywa kwamahlathiokoko utshintsho lwendalo olulandelayo lwakhokelela kwinani elikhulu lempuku, kwaye amakhalane afumana isifo seLyme bacteria kwiimpuku.
Iingxaki zezoqoqosho
Ngoku ka I-Ebbetts Pass Forest Watch (i-EPFW) , ngelixa ukucoca kunokubanceda kuqoqosho kubanini beeplanga, iikontraki kunye nabasebenzi abafumani zibonelelo ezifanayo. I-EPFW yalatha kwidatha ebonisa ukuba ulonwabo olunxulunyaniswa namahlathi esizwe lunokungenisa imali ephindaphindwe kangange-31 njengokugawulwa kwala mahlathi esizwe e-United States, kwaye ulonwabo lunokuvelisa imisebenzi ephindaphindwe kangange-38.
Iingxaki zobuhle
Ngenxa yokusikwa, ihlathi elidala elinamandla likhangeleka lincitshisiwe kwaye linqabile. Ixabiso lobuhle bamahlathi linexabiso lezoqoqosho kuba amahlathi amahle anokunyusa ixabiso lepropathi yendawo ethile kwaye atsale abakhenkethi. I-EPFW ithetha ngendlela ubuhle bendalo bamahlathi eSierra Nevada abubambe ngayo ngokubhekisele kubakhenkethi nakubantu abanomdla wokufuduka.
Umda kuLonwabo oluDlulileyo
Ukuzonwabisa yenye yeendlela apho ilahleko yendawo yokuhlala ebangelwe kukususwa kokucoca inokuhlangana nezinye iziphumo zokucoca kuba abantu abanomdla wokuzingela okanye ukuloba izilwanyana ezithile zasendle banokulahlekelwa lithuba lokwenza oko ngenxa yokusikwa. Ngelixa ixabiso lobuhle bendalo kunokuba nzima ukulibala, i-EPFW ibhekisa kubalo olucebisa ukuba oohola bendlela abanobuhle banokungenisa kangange-32,500 yeedola ngemayile.
Iindlela zokuCoca
Ngelixa ngokuqinisekileyo zininzi izinto ezingathandekiyo ekususeni ukucoca, kukho izigqibo ezintle ezinokuba luncedo kakhulu kwindalo. Ngokwe- Imyuziyam yaseSierra Logging Phambi kokuba kuvunywe isivuno se-clearcut, kufuneka kuhlangatyezwane neemfuno ezininzi ezibandakanya. 'ukutshabalalisa amahlathi, ukukhukuliseka komhlaba, ukukhuselwa kwezilwanyana zasendle kunye nokukhuselwa komgangatho wamanzi.' Umbutho woPhuculo lweWoodmoreland Woodlands (WWIA) ithi imbono yokusika okucacileyo iyingozi kwindalo ayichanekanga. Umbutho uthi:
- Ukucanda ukusika yeyona ndlela isebenzayo yokuhlaziya ihlathi elinemithi esempilweni.
- Iinkqubo ezilungileyo zamahlathi zibandakanya ukucanda ngokugawulwa kwamaplanga ekubeni yimveliso engeyiyo injongo.
- Ukusika okucacileyo okususa yonke imithi engaphezulu kweesentimitha ezimbini ukukhuthaza ukuhlaziywa kwehlathi.
Unyango kumahlathi aKhuselweyo
Ukucoca ibonelela ngendlela yokususa amahlathi amileyo kunye nezigulo kwaye inike nethuba lokuphinda utyale kwaye uvelise ihlathi elisempilweni. Isileyiti esicocekileyo sinika amandla okuzaliswa ngokutsha kunye nehlathi elicwangcisiweyo elibandakanya iintlobo ezahlukeneyo. Ekubuyiseleni kwakhona indalo, izityalo ebezikade zingakhuli phantsi komthi wehlathi ziya kukhula kwaye zibonelele ngemithombo yokutya entsha yezilwanyana ngelixa ikhuthaza izilwanyana zasendle ezintsha ukuba zingene.
- Umhlaba ocacileyo unika ithuba lokwenza ibhulorho phakathi kweendawo ezimbini zokuhlala. Oku kuvumela ukwahluka okukhulu kwezilwanyana kwindawo enikiweyo.
- Izityalo ezikhula kancinci, ingca kunye neentshinyela zithatha indawo ecacisa indlela kwaye zinika indawo yokuhlala izilwanyana ezincinci.
- Umhlaba ocacileyo unokudlala indima efanayo nokutshiswa okulawulwayo (ukutshiswa okumiselweyo) ukusukela oko umaleko wenkunkuma (umthi ofileyo, amagqabi, kunye nenkunkuma) isuswe ngexesha lenkqubo. Oku kunceda ukuthintela kunye / okanye ukulawula imililo yasendle.
Cacisa iiNzuzo zokuSika kuMhlaba nakuManzi
Ngokwe-WWIA, yinto engeyiyo eyaziwayo yokuba ukucima ukonyusa ukwanda komhlaba. Umbutho ukhomba kwiinkqubo ezingacwangciswanga kakuhle njengeyona nto ibangela ukhukuliseko, hayi ukucoca. Ukucoca indawo ekuthiwa yicrcutcut kuthiwa kuya kunceda umhlaba kunye namanzi. Ezi zibonelelo zibandakanya:
- Amandla omhlaba okugcina amanzi ayaphucuka kwiindawo ezicocekileyo.
- Inkqubo yendalo iyakwazi ukuxhasa ihlathi elisempilweni.
- Ukuqokelelwa kwamanzi esitshingitshane kukhokelela kuphuculo lwendalo kwaye ngamanye amaxesha kunokwenza indalo entsha.
- Ukuhamba kwamanzi kuyonyuswa kwimihlaba ecocekileyo kwaye kuzisa intabalala kwezi ndawo.
- Ukuhamba komjelo kuphuculwe kakhulu ngamanzi amancinci asetyenziswa yimithi.
Izibonelelo zeMali zokuCoca amaHlathi okusika
Kukho iimpikiswano zokuba ukucoca ngokucacileyo kunika izibonelelo ezininzi zezezimali. Impikiswano enye ibanga ukuba iinkampani ezininzi zemithi zenza inzuzo enkulu ngokusika ngokukhetha kunokuba zisenza zisuswe. Ukusika okukhethiweyo kusekelwe kwixabiso lemarike, ngelixa ukucoca kunika umxube wemithi, eminye ayilungelanga i-veneers okanye olunye usetyenziso. Abanye baphikisa ngelithi kubiza imali encinci ukucanda kunokususa imithi ukusika ngokukhetha. Kuxhomekeke kweliphi icala okholelwa kulo, iinkampani zemithi ziyayibona inzuzo eyonyukayo kwimithi ecocwe ngokucoceka.
Cacisa ukuGuqula iiNdawo eziGuqukayo
Ngelixa ezinye zeziphumo ebezingalunganga zokucoca zicacile, zikhona ezilungileyo nezilungileyo, ngakumbi amahlathi angenampilo. Ukucima ukusika kunokuguqula indawo ngeendlela ngeendlela ezinokuba ngumxube wokulungileyo nokungalunganga. Ngaphambi kokwenza isigqibo malunga nokususa ipropathi yakho, jonga yonke le micimbi.
