As a nidalee player, you'll generally spend your time playing weak or mediocre lanes.
Real bullies with killing potential don't belong with you.
The logical consequence : You're gonna fight against agressive lanes, or get a farmfest.
Not seen as often anymore, but still a powerful CC maniac.
Being a bushcamper, you'll either want to make sure you're trapping CONSTANTLY (Consider a Chalice if you're in mana issues), or you'll get some spare wards. Alistar's killing potential is just too much for you to handle.
Bitchcrank won't be troublesome for you. Either staying at long range, safely away from his hooks, or in the brush with your extra mobility, the robot won't be your main issue here. If you DO get grabbed, it's game over though. With the recent nerf changing into Cougarform won't give you extra tank stats anymore, so just stay in human and heal asap if you find yourself getting fisted.
Caitlyn is annoying. Her long range harassment is difficult to heal upto, and make sure your carry knows your heal costs mana and has a cooldown (Yell at him if he keeps taking the peacemakers to the face). Caitlyn only gets really dangerous when paired with additional hard cc though, if that's the case opt for bushcontrol and pray your jungler will gank for you.
Leona is similair to Alistar, with the exception of her lack of displacement abilities. She's seen quite often recently, with a good reason. Especially post-6 her stunlock will be too much for you to handle. Be cautious.
Nami is just "one of those" champions that can completely go either way. If you're not a total retard walking into the bubble (OOH SHINY) you should be o.k, as her heal/dps isn't that noteworthy and her ultimate is too slow for you. Your carry may not like her as much though. Make sure you poke at her often, losing her damage is a nice perk when she's forced to heal often.
Sona is beyong broken. Her autoattacks with Power Chord are insane, and she'll be able to trade with you evenly if you don't hit spears. Abuse the fact that she'll push the lane, and make sure you position yourself behind her post-6, we can't see nidalee dancing..
Taric can go either way, and hence is listed in both passive and agressive. His stun relies on surprise-effects, so your traps should keep him at bay.
As mentioned before, if you see he's eating them on purpose so he can surprise your carry, just put a second or even third point in it early, skipping the heal or spear for now. It'll make him regret taking bushes for granted.
Tristana is not overwhelmingly difficult to lane against, but certainly noteworthy on the agressive side. Paired up with someone like Thresh or Zyra (Snaring are her friends) her Rocket Jump will do annoying amounts of damage. To deal with her long range, prevent her from freely moving about with your spears. You'll need a gank or kill on her though, so make sure your carry knows that passive farming won't win you the lane.
Zyra is a strange support. Because of her root, you'll die if she catches you. Easy as that. Luckily, bushwacks counter plants right?
An uncovered bush is lethal here. The high travel speed on her snare is too dangerous to ignore, so make sure you're on your toes and warding properly in this lane.
I don't know what to think of thresh. In my eyes he's a fairly solid pick with a bit of cc, but his weakness lies in his mobility and passive soul gathering. It's always funny to put a bushwack on a loose soul, making him choose between losing a stack and losing health.
Be wary of his chains, the initial swining animation should be enough for you to guess the direction it's heading and generally you can hop out in time. If you do get caught, don't panic and jump away to his sides, that way his knockback won't be useful.
Don't try to kill him unless you land something like Condemn on him, the lantern will make your life miserable.
Ofcourse there's also passive lanes ;
Ashe is just...Ashe. She's the rightclickonly carry that you don't have to fear. Her hawkshot does nothing but make your dragon sneaks slightly harder, and even when paired with a heavy burst/cc champ (like Leona) you won't be threatened by her.
As a result, you'll just have to make this a farmlane. Keep up the spearpoke, and make sure you don't try anything stupid. Once she has her ult, she becomes fairly potent in terms of kills.
Corki just has nothing on you, really. He can check bushes (Which you won't be in anyway), he has short ranged Gattling Gun (You won't be in range), he's got long range poke (which you'll dodge / minionblock) and his Valkyrie has a ridiculous cooldown that'll leave him vulnerable to anything you throw at him.
Ezreal just plays the poke game, keep your minions between you and try not to mind the blonde fabulous explorer too much. Just battle it out with the support and let your carry decide about things.
Graves is tricky when paired with high cc champions, but because of his short ranged burst you shouldn't have too much trouble vending him off. A nice thing to note is that when he smokescreens you, even revealed targets will be invisible. Then again, you just jump out in his direction and end up killing him anyway.
Janna is heavily underplayed, but still strong. Try to find a window where her shield is off cooldown (For example by throwing a spear at her) and try to jump in for a quick burst and disengage. She shines at extended engages, so try to be swift when playing against her.
Loljk nobody plays karma.
Kill him everytime he tries anything. His long range poke is annoying but easily dodged (if you pay attention that is), make sure to keep your carry healthy as he DOES deal a ton of damage if he gets the chance and try to get your jungler to give you a gank.
Lulu pokes. Lulu pokes a lot. Lulu pokes a lot with glitterlance.
Just spear that little fairy, she can shield and run but that leaves her carry open for aa's. It's good to note that while her shield is on cooldown you're free to harass her as if statutory rape was your middle name ; hit her hard, hit her often.
Nunu recently got quite a hefty nerf, but he's still strong because of the meta. The iceball is a direct counter to your heal, except for the fact that his is like a snowball and yours a bullet (No travelspeed while your heal is instant). Also he needs to sustain by eating minions, which is a perfect oppertunity to spear him or even cougar and swipe while he's enjoying a snack.
Quit playing Blind pick. 2 SHENS OMG.
Sivir is not vaible, punish her for picking it. You should be careful about hte spellshield though, make her use it by dropping bushwacks on her chilling spots so you're free to spear her. That being said, it's gonna be a bit hard for you to damage her with your spears so consider spending a bit more points in your heal rather than damage, and make it a passive lane.
Soraka doesn't like magic damage (Since her heal only gives armor) so make use of it. The silence is annoying and she's a living mana battery so sustain will be an issue, but just focus on hitting her a few times and while heal is on cooldown go manmode on their carry.
As noted in the "Agressive" part ; Taric is too versatile to really discuss here. Try to see if he's into playing agressive or not, and switch up your playstyle accordingly.
Varus just has a fairly troublesome poke with his Q, but he's not last hitting while he charges it. Make sure you go in Cougar form as he tries to hit you, so you'll jump aside, take no damage, make him miss cs and spend mana! He should catch onto the "kk let's just farm" idea quickly, which is when your awesome jungler comes along and kills the guy.
Twitch is bad, get a vision ward for the center of the lane, heal your carry and just hit a lot of spears on his face. If you're a hobo without gp/10 runes and vision wards are too expensive, just level your bushwack a bit, buy mana pots and place em all around the map so he won't get his Ambush to be of any effect.
Twitch is actually pretty viable right now. Thing is, he doesn't like Nidalee at all. Cats eat rats! Use your hightened mobility to dodge his Vials (It's REALLY important to camp bushes for this, as boots are not your main priority).
